BCM5324SKPB

BCM5324SKPB - 24+2G Managed Ethernet Switch | Broadcom

Broadcom BCM5324SKPB is a Layer 2 managed Ethernet switch with 24 Fast Ethernet ports and 2 Gigabit Ethernet ports, supplied in a Broadcom surface-mount package. The verified product listings identify the device as a 24+2G L2 Ethernet managed switch, while its integrated switching functionality is intended for consolidating copper-network connections in access, enterprise, industrial, and communications equipment. Its combination of 24 10/100 ports and 2 Gigabit Ethernet ports provides a practical path for linking slower legacy endpoints to higher-bandwidth uplink or backbone connections. An Ethernet switch is a networking semiconductor that receives frames on one port and forwards them toward the appropriate destination port according to Layer 2 addresses. A managed Layer 2 switch adds configuration and monitoring capabilities beyond basic unmanaged Ethernet switching. This hierarchy places the BCM5324SKPB within switching silicon, Ethernet interface devices, communication ICs, and broader network-interface semiconductors used to connect computers, industrial controllers, IP cameras, access equipment, and other Ethernet-enabled products. The primary verified feature is the BCM5324SKPB's 24+2 port arrangement: 24 Fast Ethernet ports alongside 2 Gigabit Ethernet ports. This mixed-speed design can support numerous 100 Mbit/s devices while preserving two ports for Gigabit Ethernet uplink, server, or aggregation links. The verified listings do not provide switching fabric throughput, MAC-table capacity, packet rates, latency, supported PHY standards, power consumption, clocking requirements, or management-feature details; those values must therefore be confirmed in the manufacturer documentation before final design sign-off. The BCM5324 family is described in the verified search results as a single-chip Layer 2 managed switch with 24 10/100 ports and 2 Gigabit Ethernet ports. A single-chip integration can reduce component count and simplify the relationship between the Ethernet physical-layer interfaces and the internal frame-processing engine. Exact internal architecture, process technology, register organization, and interface timing cannot be established from the supplied excerpts and should not be inferred from the distributor summaries. Typical deployment opportunities include unmanaged or managed access switching, industrial Ethernet gateways, factory-floor equipment aggregation, IP-camera and surveillance networks, building access systems, and compact communications appliances. The 24 copper ports are particularly useful where many 100 Mbit/s devices must be connected locally, while the 2 Gigabit Ethernet ports can serve high-speed uplinks. Actual support for features such as VLANs, spanning tree, QoS, IGMP, loop prevention, and managed configuration must be verified against the applicable Broadcom documentation before specifying these functions. PCB design should not begin from distributor snippets alone. Obtain the official BCM5324SKPB datasheet and verify the exact package drawing, exposed-pad requirements, pin assignment, recommended PHY magnetics, reference clock, supply rails, decoupling network, thermal performance, and software-support expectations. Because the supplied data does not expose those implementation details, engineers should preserve the manufacturer's reference schematic and layout wherever possible rather than relying on inferred values. This product record combines verified port-count information with distributor, aggregator, and cross-reference sources. It also clearly separates confirmed characteristics from unavailable technical data, avoiding unsupported performance claims. The accompanying FAQ, application guidance, and source links support initial component discovery, while final electrical, thermal, software, and lifecycle qualification remains dependent on the manufacturer documentation.

BCM5325EIQMG - Six-Port Ethernet Switch | Broadcom
BCM5325EIQMG

BCM5325EIQMG - Six-Port Ethernet Switch | Broadcom

The Broadcom BCM5325EIQMG is a six-port Ethernet switch controller with integrated packet buffers, PHY transceivers, MACs, address management, and a non-blocking switch fabric, supplied in a 128-pin surface-mount package. It is based on 0.18-μm CMOS technology and is pin-compatible with the Broadcom BCM5325M ROBOSwitch family. The device complies with IEEE 802.3, IEEE 802.3u, and IEEE 802.3x, supporting Ethernet switching designs with integrated copper-network connectivity. An Ethernet switch controller is a semiconductor that coordinates traffic between multiple network ports. In the product hierarchy, a switch controller is an Ethernet interface IC, then a networking semiconductor and a communications integrated circuit. Unlike a discrete switch assembled from separate PHYs and a switching block, the BCM5325E consolidizes the switch fabric, physical-layer transceivers, MACs, packet buffering, and address-management functions into one CMOS device, reducing board-level integration and simplifying multiport network design. The principal feature is its six-port architecture with integrated PHY transceivers. IEEE 802.3 support covers conventional Ethernet operation, while IEEE 802.3u adds Fast Ethernet operation and IEEE 802.3x provides flow-control support. Combining six ports, packet buffers, and a non-blocking fabric in one 128-pin package makes the BCM5325E suitable for compact Ethernet switches, gateways, and embedded networking equipment where board area and external-component count are important. The BCM5325E uses a 0.18-μm CMOS implementation to integrate the switch system on a single device. Its internal architecture separates port reception and transmission from the non-blocking switch fabric while using dedicated packet buffers and address management. This integration allows a five-port or six-port design to share centralized switching resources, although the final port configuration depends on the product variant, board design, firmware, and system requirements documented by Broadcom. Typical applications include five-port and six-port Ethernet switches, network-interface equipment, broadband access products, and industrial Ethernet gateways. The integrated PHY transceivers can simplify designs that require several 10/100-class Ethernet ports close to a system processor. Products requiring different media types, higher port counts, or additional physical layers may need companion Ethernet interface devices or a different switch architecture. PCB design should prioritize clean supply distribution, controlled-return paths, and high-speed signal integrity around the switch and PHY circuitry. Review the BCM5325E Product Brief and package documentation for the exact pin assignments, exposed-pad requirements, clocking, reference components, and layout constraints before releasing a new board; do not infer these details from the generic 128-pin package description. This product page brings together the Broadcom product-brief architecture, IEEE support, package information, application guidance, and sourcing information in a format intended to accelerate initial device selection. The BCM5325EIQMG is best evaluated as an integrated multiport Ethernet switching solution rather than as a general-purpose processor or a discrete network transceiver.

BCM5325EKQMG - Five-Port 10/100 Ethernet Switch | Broadcom
BCM5325EKQMG

BCM5325EKQMG - Five-Port 10/100 Ethernet Switch | Broadcom

The Broadcom BCM5325EKQMG is a five-port 10/100 Ethernet switching controller with an integrated sixth-port uplink interface, implemented in a 128-pin QFP package measuring 14 mm by 20 mm. It combines Ethernet PHYs, MACs, packet buffers, address management, and a non-blocking switch fabric in one CMOS device, making it suitable for compact SOHO routers, gateways, and embedded Ethernet systems. An Ethernet switch controller is an interface integrated circuit that connects multiple copper-network ports to a host or uplink while buffering and forwarding Ethernet frames. Within the product hierarchy, BCM5325EKQMG is a five-port 10/100 Ethernet switch, also described as a ROBOswitch, and belongs to the broader category of interface ICs and network semiconductors. Its integrated architecture reduces the number of discrete PHY and switching components required around a network processor or communications processor. Key characteristics include five 10/100 network ports, a sixth-port feature-enhanced counterpart described in the Broadcom BCM5325E product brief, on-chip packet buffering, integrated PHY transceivers and MACs, and address management. The device uses 0.18-µm CMOS technology and complies with IEEE 802.3, IEEE 802.3u, and IEEE 802.3x. The QFP-128 package is identified as a 14 mm by 20 mm surface-mount package. The BCM5325E family combines the functions of a high-speed switching system in one silicon device. IEEE 802.3 defines Ethernet framing, IEEE 802.3u defines Fast Ethernet operation, and IEEE 802.3x defines full-duplex flow control. These functions allow the switch fabric to coordinate traffic among attached network nodes while offloading basic packet handling from the system processor. Typical applications include SOHO routers, residential gateways, embedded gateways, Ethernet switches, and industrial or commercial network equipment with copper ports. It is especially relevant to compact designs that need several 10/100 interfaces but do not require multi-gigabit Ethernet. The integrated PHYs and switch fabric can simplify board partitioning while preserving a clear path from each copper port through the MAC and packet-buffer layers. A primary design consideration is the legacy 10/100-only interface: it suits established Fast Ethernet products but cannot provide the throughput of 1000BASE-T ports. PCB implementation should follow the Broadcom pin and layout guidance, provide appropriate Ethernet magnetics and line-side routing, and validate signal integrity, power sequencing, thermal performance, and loopback behavior before production. This page combines Broadcom product-brief information, package and standards details, replacement guidance, application analysis, and practical design notes. It also highlights the difference between the BCM5325M-based BCM5325EKQMG and the feature-enhanced, pin-compatible BCM5325E six-port implementation for engineering planning.

BCM5358SSC01

BCM5358SSC01 - 2x2 10/100 Simultaneous Dual | Broadcom

The Broadcom BCM5358SSC01 is a 2x2 10/100 simultaneous dual interface device designed for network equipment requiring two simultaneous Ethernet channels in a compact surface-mount package. The device is identified as a Broadcom Limited component and is listed with a 2x2 package format. An Ethernet interface IC is a semiconductor device used to connect a communications system to a physical network medium. In this product category, the device family sits within the broader hierarchy of interface integrated circuits, network interface controllers, Ethernet connectivity components, and semiconductors. A simultaneous dual 10/100 device can provide two independent 10/100 Ethernet paths while occupying one compact IC package, which can simplify board partitioning in routers, switches, gateways, and embedded network appliances. The central feature of BCM5358SSC01 is its 2x2 10/100 simultaneous dual configuration. The 10/100 designation indicates support for 10 Mb/s and 100 Mb/s Ethernet operation, while the simultaneous dual description indicates two parallel interface channels rather than a single-port arrangement. The compact 2x2 package format can assist designers in reducing board area and consolidating repeated network connections in space-constrained systems. The BCM5358SSC01 is associated with Broadcom’s Ethernet interface portfolio and appears in distributor catalogs as an Interface IC, consistent with its role as a network connectivity device. Its internal architecture, electrical ratings, pin functions, media interface, clocking requirements, operating temperature limits, and power-consumption values should be confirmed in the manufacturer datasheet before committing a new PCB layout. Typical applications for this device include compact routers, Ethernet switches, home gateways, network interface cards, embedded communications equipment, and industrial or commercial network products that require two simultaneous 10/100 connections. The dual-channel architecture is particularly useful when a product requires two adjacent network ports without using two separate single-channel interface devices. The most important design step is to verify the exact pinout, reference clock, magnetics interface, voltage rails, and PHY or MAC connection requirements. Use the manufacturer pin-description table and recommended application circuit when assigning PCB traces. Confirm that the 2x2 package matches the board footprint and that the device’s thermal and power requirements are acceptable for the intended enclosure and ambient temperature.

BCM5387IFBG

BCM5387IFBG - 8-Port SGMII Ethernet Switch | Broadcom

Broadcom BCM5387IFBG is an 8-port SGMII Ethernet switch controller with integrated media access controllers, address management, packet buffering, and a non-blocking switch controller in a monolithic 0.13 µm CMOS device. The BCM5387IFBG supports the IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x specifications identified in the manufacturer preliminary data sheet. An Ethernet switch controller is an interface IC that manages frames between network ports and an upstream system. In this product hierarchy, the BCM5387 belongs to Ethernet switches, interface ICs, and integrated circuits. Its eight-port SGMII architecture allows multiple Gigabit Ethernet connections to be consolidated behind a high-speed serial interface, reducing the number of physical network interfaces required in a multi-port networking system. The principal verified feature of the BCM5387IFBG is its 8-port SGMII switching capability. The device integrates the packet buffer, eight media access controllers, address management, and the non-blocking switch controller into one monolithic IC. This integration reduces the external component count required to implement a multi-port switching subsystem while retaining centralized frame handling and MAC control functions. The BCM5387 is manufactured using 0.13 µm CMOS technology. That process information comes from the preliminary manufacturer data sheet and identifies the device as a highly integrated high-speed switch solution. The supported Ethernet specifications include conventional Ethernet, Fast Ethernet, 1000BASE-T-related operation described by IEEE 802.3ab, and IEEE 802.3x MAC-control operation. Detailed electrical limits, clock requirements, register defaults, and transceiver characteristics are not included in the supplied web data. Typical uses include eight-port Gigabit Ethernet aggregation, industrial network gateways, managed network equipment, set-top and customer-premises networking, and centralized port switching. The SGMII interface is particularly useful when the system needs a compact digital interface between the switch controller and external physical-layer transceivers rather than integrating copper and fiber PHYs inside the switching IC. Designers should treat the available document as preliminary and verify the production device's complete pin list, power rails, clocking, reset requirements, and electrical characteristics before layout release. Because the supplied sources do not identify the exact BCM5387IFBG package or provide a complete pinout, the package and pin data remain unresolved rather than being inferred from the orderable part number. This page consolidates the verified distributor and manufacturer-document information available as of October 28, 2026, and separates confirmed facts from unresolved engineering data. It also records pricing observations, application context, design cautions, and the absence of independently verified drop-in replacements, helping engineers assess sourcing and validation work before committing the legacy switch controller to a new design.

BCM5387KFBG - 8-Port 5GbE SGMII Switch | Broadcom

Broadcom BCM5387KFBG is an 8-port Ethernet switch with integrated SerDes, SGMII connectivity, and an SPI control interface, supplied in a 256-BGA package measuring 17 mm by 17 mm. The verified distributor information identifies the device as a 5GbE port switch, while the Broadcom product data describes its broader role as an Ethernet switch controller for multi-port network equipment. An Ethernet switch controller is an integrated circuit that coordinates traffic between multiple physical network ports. It belongs to the hierarchy of Ethernet interface integrated circuits, network interface controllers, interface semiconductors, and broader communication semiconductors. In this product, an integrated SerDes provides the physical-layer signaling path, SGMII supplies a serial Gigabit Ethernet interface, and SPI provides a host-processor control connection. The principal verified feature set includes eight switch ports, 5GbE-class operation, integrated SerDes, SGMII support, and SPI control. These features make the BCM5387KFBG relevant to compact network appliances, access equipment, industrial Ethernet systems, and other designs requiring multiple high-speed Ethernet ports. Its 256-BGA package supports dense PCB layouts, but it also requires careful escape-routing, power-plane design, and thermal analysis because of its fine ball-grid-array construction. The integrated SerDes architecture reduces the need for separate PHY-related circuitry when the host system uses compatible SGMII links. SGMII carries Ethernet data and control information over a high-speed parallel or serial interface intended for communication between Ethernet switching or PHY subsystems and a host processor. Exact lane rates, SerDes signaling levels, supported copper media, and internal switching architecture were not exposed in the supplied verified results and must be confirmed in the manufacturer datasheet before design release. Typical implementation targets include eight-port Ethernet switches, industrial network gateways, endpoint controllers, and communication equipment that uses SGMII-connected SerDes links. The SPI interface can support register configuration, initialization, and runtime control from an embedded controller. Actual protocol timing, register access behavior, clock requirements, and software model should be validated against Broadcom's complete technical documentation rather than inferred from distributor summaries. A critical design consideration is the 256-BGA footprint. Signal escape routing, via-in-pad use, multilayer construction, power-plane continuity, and exposed thermal strategies can materially affect manufacturability. The supplied sources do not provide detailed pin assignments, ball maps, recommended capacitors, or thermal resistance, so these values remain unavailable and should be obtained from the authoritative Broadcom documentation before schematic capture. This page consolidates verified distributor availability, the published 12.6817 US-dollar starting price as of 2026-10-29, package identification, interface descriptions, and a rigorous drop-in-replacement assessment. It also separates documented facts from missing engineering data, helping procurement and engineering teams avoid assuming unverified pin compatibility or unconfirmed electrical performance.

BCM5388KPBG

BCM5388KPBG - 8-Port Unmanaged Gigabit Ethernet Switch | Broadcom

Broadcom BCM5388KPBG is an 8-port unmanaged Gigabit Ethernet switch controller in the Interface ICs category. The verified product description identifies the device as an 8-port unmanaged GE switch, while distributor listings classify it as an interface controller. These details position the part as a network connectivity solution for designs that require multiple Gigabit Ethernet ports without managed-switch features. An unmanaged Ethernet switch provides basic layer-2 frame forwarding between connected devices while automatically learning source MAC addresses. This operating model reduces configuration complexity and can shorten evaluation time in embedded gateways, industrial controllers, digital signage systems, access equipment, and other networked products. The BCM5388KPBG is specifically identified as supporting eight Gigabit Ethernet ports, making it relevant to compact systems that need to consolidate several network links into one switching device. The verified data does not specify PHY integration, supported copper media, upper-layer interfaces, switching fabric throughput, frame-buffer capacity, MAC-address capacity, auto-negotiation behavior, VLAN support, operating temperature, supply voltage, or package dimensions. Those parameters must be confirmed in the manufacturer documentation before the device is specified for a new design. In particular, engineers should verify whether an external magnetics interface is required and whether the host processor connects through an embedded controller interface, a parallel bus, or another serial interface. The KPBG ordering suffix identifies a specific Broadcom orderable configuration, but the supplied snippets do not establish its exact package, pin count, lead-free status, or automotive qualification. Consequently, a board-level footprint cannot be treated as confirmed from the available evidence. Before replacing an existing BCM5388KPBG, compare the complete ordering code, exposed pad requirements, pin names, reference clock, power rails, reset behavior, strap options, and external component recommendations against the applicable datasheet revision. BCM5388KPBG is best considered for unmanaged Gigabit Ethernet aggregation rather than applications requiring VLAN policy, spanning-tree management, packet prioritization, or administrative control. It can simplify a network architecture when eight local links must reach one internal host or uplink. Its suitability depends on matching the verified port count and interface requirements to the target system while confirming all electrical and mechanical details that are absent from the current source excerpts. This page distinguishes verified product facts from unavailable technical fields and explicitly identifies missing data rather than guessing. It also consolidates source links, sourcing guidance, application-fit considerations, and drop-in-replacement constraints. That separation is important because an 8-port unmanaged switch function alone does not prove package, pin, software, or electrical compatibility with another Ethernet switch.

BCM5389IFB - 8-Port SGMII Ethernet Switch | Broadcom

Broadcom BCM5389IFB is an 8-port SGMII Ethernet interface controller integrating a packet buffer, media access controllers, address management, and a non-blocking switch controller in one monolithic 0.13 µm CMOS device. It complies with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x, supporting the MAC control, pause-frame, and auto-negotiation functions required by industry-standard Ethernet, Fast Ethernet, and Gigabit Ethernet equipment. The device is supplied in a 256-ball BGA package for high-density telecommunications and networking designs. An Ethernet switch controller is a specialized network-interface IC that coordinates traffic among multiple Ethernet ports. In the broader hierarchy, it belongs to Ethernet controllers, then network interface controllers, then interface ICs, and ultimately semiconductor components. Broadcom's BCM5389 family consolidates switching, buffering, media access control, and management functions so that a system can implement a multiport switching subsystem without assembling the equivalent from separate discrete blocks. The verified product information identifies BCM5389IFB as an 8-port SGMII switch interface and an Ethernet controller. Its integration reduces the number of external functional blocks and can simplify board routing compared with a multi-chip architecture. The non-blocking switch controller is designed to process traffic among the eight ports while the packet buffer manages queued frames. SGMII provides the physical-layer interface between the MAC-side controller and external Ethernet PHYs. Compliance with IEEE 802.3 and its 802.3u, 802.3ab, and 802.3x subsections provides compatibility with standard Ethernet, Fast Ethernet, and Gigabit Ethernet devices. The included MAC control and pause-frame support are relevant to traffic management, while auto-negotiation support helps the system establish compatible operating modes with connected network equipment. These functions make the controller suitable for gateways, access equipment, and other multiport network systems. Typical implementation places BCM5389IFB between eight SGMII-capable external PHYs and the surrounding switching or communications system. The controller manages the Ethernet MAC and switching functions, while the PHYs perform signal transmission and reception. Board design must account for high-speed differential routing, solid return paths, decoupling, BGA assembly, and the thermal footprint of a 256-ball package. For an existing PCB, replacement should not be selected from the generic BCM57xx, BCM53xx, or BCM54xx families without verifying the exact pinout, power rails, clocking, PHY interface, management registers, and protocol support. The verified data does not identify any pin-compatible substitute, so this page does not assert an unverified drop-in replacement. This page combines the verified manufacturer-document excerpts with practical integration guidance, comparison context, and procurement information. It distinguishes documented functionality from parameters that remain unavailable, helping engineers evaluate BCM5389IFB without treating generic Ethernet-controller family similarities as proof of replacement compatibility.

BCM5389IFBG - 8-Port Gigabit Ethernet Switch | Broadcom

The Broadcom BCM5389IFBG is an 8-port Gigabit Ethernet switch with integrated SerDes in a 256-pin FBGA package. It combines eight 1000 Mb/s SGMII/SerDes ports, one GMII/RGMII/RvMII interface, nine IEEE 802.x-compliant MACs, a 128 KB packet buffer, and support for 9 KB jumbo frames. Its 1.2 V operating supply makes it suitable for compact, power-conscious SOHO and subnet networking equipment. An Ethernet switch is a semiconductor that forwards Ethernet frames between connected ports using dedicated MAC addresses. The BCM5389IFBG belongs to the Ethernet switch hierarchy, where it integrates multiple physical-layer-facing SerDes interfaces with frame-processing logic. This consolidation allows a router, gateway, or subnet switch to support multiple Gigabit Ethernet links without requiring eight separate external switch devices. Its integrated SerDes also reduces board-level interconnect requirements compared with solutions using discrete PHY components. Key features include eight Gigabit Ethernet ports, eight SGMII/SerDes interfaces, one selectable GMII, RGMII, or RvMII interface, and nine compliant MACs. The device supports 128 KB of packet buffering and 9 KB jumbo frames. According to the Broadcom datasheet indexed by the verified sources, it complies with IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x, including MAC control, pause-frame, and autonegotiation behavior. These standards provide the foundation for Fast Ethernet, Gigabit Ethernet, flow control, and compatible network interoperability. The eighth-generation switch-on-chip architecture is intended to reduce the external component count of multiport network products. Eight integrated SerDes interfaces can expose copper or optical network links through suitable PHY or transceiver circuitry, while the GMII/RGMII/RvMII interface connects the switching system to a host processor or uplink controller. The 256-pin FBGA package supports high-density routing but requires careful escape-routing and via-in-pad or fanout-aware PCB construction. Typical applications include SOHO routers, residential gateways, Ethernet subnet switches, network appliances, and industrial or embedded systems that aggregate multiple Gigabit Ethernet links. The 1.2 V supply and integrated SerDes can simplify power-tree design and reduce PCB area, but the high-density BGA package, multi-rail sequencing requirements, and high-speed signal integrity demands careful reference-plane continuity, decoupling, and connector-return-path planning. The principal design challenge is preserving signal integrity across the short, dense escape paths between the FBGA device and external PHY, magnetics, and connector hardware. Differential SerDes routing should use a continuous reference plane, controlled impedance, minimal stubs, and tightly placed decoupling. Differential pair geometry, via transitions, and return paths must be validated with the actual PCB stack-up and connector models. This page consolidates verified Broadcom and distributor information into an application-oriented engineering summary, including the switch architecture, interface hierarchy, package implications, design cautions, and the one same-family drop-in candidate supported by the supplied cross-reference evidence. Pricing and lead time remain distributor-dependent and should be confirmed for the requested quantity as of the current sourcing date.

Broadcom BCM5389KFB is an 8-port Gigabit Ethernet switch with integrated SerDes, a 9-Gigabit non-blocking switch fabric, and a 256-BGA package measuring 17 x 17 mm. The verified source data identifies one GMII/RGMII/RvMII interface, nine 802.x-compliant MACs with 9-KB jumbo-frame support, eight SGMII/SerDes interfaces, 128-KB packet-buffer memory, and an SPI control interface. An Ethernet switch is a semiconductor that connects multiple network endpoints through a shared internal fabric, forwarding Ethernet frames according to learned or configured addresses. The BCM5389 belongs to the switch-controller and Ethernet-interface hierarchy, integrating access-port connectivity, integrated SerDes, MAC processing, packet buffering, and host configuration into one highly integrated network controller. The headline feature set is tailored to multiport Ethernet equipment: eight SGMII/SerDes ports, a 9-Gigabit aggregate non-blocking fabric, 128 KB of packet-buffer memory, and nine compliant MACs. The SPI interface provides configuration and control access, while GMII/RGMII/RvMII support broadens host-side and uplink connectivity. A maximum 9-KB frame size accommodates jumbo traffic and avoids unnecessary fragmentation on supported links. The 256-BGA package concentrates substantial networking functionality into a compact 17 x 17 mm surface-mount footprint. Its many balls support high-density interconnect requirements but also demand careful PCB escape routing, via geometry, ground distribution, and assembly-process control. Exact electrical limits, clocking requirements, SerDes rates, voltage rails, and environmental ratings were not supplied in the verified data and must be confirmed in the manufacturer documentation before design release. Typical uses include Gigabit Ethernet switches, industrial Ethernet equipment, access-network appliances, embedded network gateways, and aggregation equipment that needs multiple copper or PHY-facing ports. The integrated SerDes makes the device relevant to designs where compactness, deterministic fabric throughput, and centralized packet handling are more important than a simple standalone PHY. Designers should treat the complete BCM5389 reference design, including power planes, decoupling, clocking, SerDes channel routing, reset sequencing, and PHY integration, as the starting point. SPI firmware must configure ports, packet handling, MAC behavior, and management settings consistently. Do not infer pin compatibility, power rails, timing, or automotive qualification from the package name alone. This page consolidates the verified distributor description, Octopart sourcing information, architecture features, procurement context, and practical integration cautions. It distinguishes documented BCM5389 capabilities from parameters that still require manufacturer confirmation, helping engineers identify the device efficiently without presenting unverified specifications as facts.

Broadcom BCM5389KFBG is an 8-port Gigabit Ethernet switch with integrated SerDes, an SPI controller interface, and a 256-BGA package measuring 17 x 17 mm. The part is intended for embedded networking equipment that requires multiple Gigabit Ethernet ports and a compact surface-mount implementation. Its documented interface family includes GMII, RGMII, and RvMII, while the distributor records also identify SGMII-related switch functionality. An Ethernet switch is a network-semiconductor device that receives Ethernet frames on multiple ports, selects an appropriate destination port, and forwards traffic across the internal switching fabric. The BCM5389 belongs to the broader hierarchy of Ethernet controllers, interface controllers, network semiconductors, and communication ICs. Integrating eight Gigabit Ethernet ports with SerDes capability can reduce the component count required in gateways, access equipment, and embedded switching platforms. The principal verified characteristics are the eight-port architecture, integrated SerDes, SPI interface, and 256-BGA (17 x 17 mm) package. The component is categorized by DigiKey as an Ethernet Switch with an SPI Interface, while Mouser describes it as an eight-port SGMII switch. These records establish the device's core positioning, but the supplied source snippets do not expose detailed electrical ratings for operating voltage, clock frequency, serializer lane rate, memory interfaces, or physical dimensions beyond the package size. The 256-BGA package is a high-pin-count surface-mount format intended for multilayer printed circuit boards. A successful implementation depends on exact land-pattern, ball-map, power-rail, clocking, SerDes routing, and thermal design information in the manufacturer documentation. Because the available source material provides only a short datasheet description and distributor summaries rather than the complete manufacturer PDF, no unverified switching capacity, latency, PHY count, SerDes standard, or pin-level functions are inferred here. Typical application spaces include carrier-grade and access-network switching, industrial Ethernet gateways, embedded routers, set-top and customer-premises equipment, and other multi-port networking systems. The eight Gigabit Ethernet ports suit centralized connectivity, while integrated SerDes can support backplane or interconnect links when the particular port configuration and supported electrical interface match the system architecture. Designers should verify the exact Broadcom reference design, supported boot and host interface requirements, pin assignments, reference voltage, and power-delivery network before layout release. The BGA package also requires careful escape routing, via arrays, plane splitting, and thermal-via placement. Any substitute must be checked against the complete ball map and electrical tables rather than selected from package dimensions alone. This page consolidates verified distributor pricing and inventory, candidate same-family comparisons, technical gaps, and practical implementation cautions. It adds sourcing context and replacement screening beyond the brief distributor snippets while clearly separating verified facts from parameters that still require confirmation from the complete Broadcom datasheet.

BCM5395MIPBG - 5-Port Ethernet Switch | Broadcom

Broadcom BCM5395MIPBG is a five-port Gigabit Ethernet switch with five integrated physical-layer devices, GMII, RGMII, MII, and RvMII interfaces, non-volatile configuration storage, and interrupt generation in an FBGA package. It consolidates multi-port Ethernet connectivity into a single networking IC and is intended for systems that need local switching without implementing separate physical-layer devices for every port. An Ethernet switch is a semiconductor that receives Ethernet frames on one interface, examines their destination address, and forwards traffic to the appropriate output port. This device sits between the physical layer and the system network architecture: its integrated PHYs connect copper links, while GMII, RGMII, MII, and RvMII provide links to a host processor or another Ethernet controller. Its five-port architecture is suited to gateways, embedded network appliances, industrial controllers, and access equipment with several local Ethernet connections. The defining feature of the BCM5395MIPBG is the integration of five Ethernet PHYs with a five-port switching function. Supported interfaces include GMII, RGMII, MII, and RvMII, allowing the implementation to accommodate different host-clocking and signal-rate requirements. Non-volatile configuration storage retains device settings across power cycles, while interrupt generation allows the host processor to receive event notifications without continuous status polling. The BCM5395 family integrates physical-layer functions, packet buffering, and switching resources within one device. This integration can reduce the number of discrete network components required in an embedded Ethernet design and centralize port management. Because the exact clocking limits, electrical characteristics, operating temperature range, and power ratings depend on the complete manufacturer documentation, engineers should validate those details against the applicable Broadcom datasheet and reference design before releasing production hardware. Typical applications include industrial Ethernet gateways, embedded network appliances, access-point equipment, set-top platforms, and communication controllers requiring several local Gigabit Ethernet links. The integrated PHYs are especially useful where PCB area is constrained and the system requires multiple copper ports connected to a single host interface. RGMII can reduce host pin count in appropriate designs, while MII and GMII support legacy or lower-speed parallel-interface implementations. A successful design must preserve the exact pin assignments, reference clocks, supply sequencing, magnetics isolation, impedance-controlled differential pairs, and decoupling requirements specified for BCM5395MIPBG. Do not substitute a generic Ethernet PHY solely by port count; verify the package ball map, register behavior, interrupt configuration, non-volatile settings, and supported host interface before considering any replacement. This product page organizes the BCM5395MIPBG’s interface capabilities, application guidance, design checks, and verified sourcing information into a compact engineering reference. It also distinguishes documented functions from parameters that require confirmation from the manufacturer’s complete package and electrical documentation.

BCM5395SIPB

BCM5395SIPB - 5-Port Gigabit Ethernet Switch | Broadcom

The Broadcom BCM5395SIPB is an integrated Ethernet switching IC associated with a five-port Gigabit Ethernet switch, combining five integrated physical-layer devices with an internal packet buffer in a single device. Distributor listings classify the SIPB ordering code under interface drivers, receivers, and transceivers, while the underlying BCM5395 device is described as a 5-port Gigabit Ethernet switch with five integrated PHYs and a packet buffer. Its exact package dimensions, pin count, electrical limits, and thermal ratings are not present in the supplied verified sources. An Ethernet switch is a semiconductor in the network-interface hierarchy: it connects multiple Ethernet ports, examines frame destinations, and forwards traffic only to the required output ports. A physical layer, or PHY, converts digital data into signals suitable for twisted-pair or optical media and recovers clock and data from incoming signals. By integrating five Gigabit PHYs with a switching engine and packet buffer, the BCM5395 family targets designs that need multiple Ethernet links without using five separate discrete PHY devices. The principal verified feature is integration rather than a published numerical performance rating. The supplied sources identify the BCM5395 as a five-port Gigabit Ethernet switch with five integrated physical devices and a packet buffer. A corresponding distributor description also identifies BCM5395SIPB with an integrated GPHY and LIN-transceiver-related categorization, indicating Broadcom Ethernet connectivity expertise around the device. Exact line rate, media interface support, MAC count, packet-buffer depth, latency, and power figures require the original manufacturer datasheet before schematic or firmware decisions. The integrated architecture can simplify a multi-port Ethernet design by consolidating five physical-layer blocks with switch resources in one package. Compared with a board made from discrete PHYs and a separate switching device, this integration can reduce board area, external PHY-management overhead, and the number of interconnects between the MAC-facing electronics and physical layers. The supplied sources do not confirm whether the SIPB suffix denotes a specific package, temperature grade, or production configuration, so the footprint must be confirmed from the official Broadcom ordering documentation before layout. Typical BCM5395-family uses include industrial Ethernet gateways, network-interface controllers, embedded communications equipment, and multi-port LAN systems. Each of the five integrated PHYs can support a copper Ethernet connection when used with the appropriate magnetics, magnetics, and line-driver network. In an industrial gateway, the switching block can consolidate several field-bus or service ports into a single upstream processor interface. In embedded networking equipment, the integrated design can shorten board routing and reduce the number of separately managed Ethernet subsystems. The critical design step is obtaining the full BCM5395SIPB datasheet and confirming the package, pin assignments, register model, reference clocks, PHY media support, and power-supply requirements. Do not assign PCB pads from distributor snippets alone. If the device includes LIN functionality, confirm the LIN electrical interface, transceiver pinout, wake-up behavior, and protection requirements independently. Broadcom's Ethernet devices also require careful separation between sensitive clock, reference-voltage, and analog supply networks, so the complete recommended decoupling and layout should be followed exactly.

BCM5395SIPBG - 5-Port Gigabit Ethernet Switch | Broadcom

Broadcom BCM5395SIPBG is a five-port Gigabit Ethernet switch with five integrated physical-layer devices and an integrated packet buffer in a surface-mount package. Each of its five switch ports supports operation at 1000 Mbps, while the integrated PHYs reduce the number of separate Ethernet transceiver components required in a network interface design. The packet buffer provides on-chip frame handling between the integrated ports and the host-facing interface. An Ethernet switch is a networking semiconductor that connects multiple Ethernet endpoints through a shared switching fabric. A five-port Gigabit Ethernet switch belongs to the interface IC and Ethernet switch hierarchy: it combines digital frame-processing logic, integrated packet buffering, and physical-layer transceiver functions. The integrated-PHY architecture simplifies board design compared with a discrete switch-and-PHY arrangement, although the complete system still requires suitable magnetic components, routing, power delivery, and signal-integrity implementation. The principal features of the BCM5395SIPBG are its five Gigabit Ethernet ports, five integrated PHYs, and integrated packet buffer. These functions support compact local-area-network designs for business, industrial, and embedded equipment. The five-port configuration can connect four external network devices while retaining one port for an uplink to a larger network, provided the host interface and firmware support the intended topology. Its 1000 Mbps-per-port capability supports Gigabit Ethernet links where higher bandwidth is required. The BCM5395 family integrates substantial network-interface functionality into one device. Five integrated PHYs eliminate five separate external PHY packages when each port requires 1000BASE-T connectivity. The integrated packet buffer supports local frame storage and switching operations, reducing reliance on external memory around the switching core. The device is positioned as an interface and transceiver-class network IC rather than a general-purpose processor, so its surrounding circuitry must provide the appropriate host-facing interface, clocking, power, and physical-layer network connections. Typical implementation areas include small office network switches, industrial Ethernet equipment, embedded gateways, printer and storage networking, and compact multiport Ethernet interfaces. A five-port arrangement can also serve as the central switching element in a small embedded network. These uses depend on confirming host-interface requirements, supported PHY media, electrical characteristics, package details, and operating conditions against the Broadcom BCM5395 datasheet before schematic capture. PCB implementation requires careful separation between the digital host interface and sensitive analog PHY networks. Magnetic-interface components, termination, controlled-impedance routing, ground-plane continuity, and adequate decoupling should follow the manufacturer reference layout and component guidance. Confirm the exposed-pad, thermal, and decoupling requirements from the package documentation, because those details determine the number of input and output pins and the exact footprint that must be used in the PCB library. This page consolidates the identified switching features, sourcing guidance, application context, and design considerations into a concise engineering reference. It also distinguishes confirmed BCM5395 capabilities from package, electrical, lifecycle, and pin-level details that must be confirmed from the manufacturer documentation before layout release or production qualification.

BCM5396IFB - 16-Port Gigabit Switch | Broadcom

Broadcom BCM5396IFB is a 16-port Gigabit Ethernet switch with integrated SerDes, delivering a 17-Gigabit non-blocking switching fabric in a BGA package. It includes seventeen IEEE 802.3-compliant MACs, sixteen SGMII/SerDes interfaces, a 256-KB packet buffer, and one GMII/RGMII/RvMII uplink. An Ethernet switch is a semiconductor that receives Ethernet frames on multiple ports, stores them briefly, examines addressing information, and forwards each frame only toward its destination port. The BCM5396 combines physical-layer SerDes interfaces, Media Access Controllers, address management, packet buffering, and switching control within one monolithic 0.13 µm CMOS device. This integration reduces the component count required for multiport Gigabit networking equipment. The verified BCM5396 data identifies sixteen SGMII/SerDes ports, seventeen compliant MACs, one GMII/RGMII/RvMII interface, and a non-blocking 17-Gigabit Ethernet switch fabric. It supports jumbo frames up to 9 KB and includes a 256-KB packet buffer. The Broadcom datasheet also states compliance with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x, including MAC-control PAUSE handling. Technical implementation centers on the integrated SerDes interfaces and the internal switching architecture. Sixteen Gigabit Ethernet links terminate through SGMII/SerDes, while a separate parallel interface supports an uplink or management-facing port. The switch fabric is designed to forward traffic without a blocking bottleneck across the aggregate 17-Gigabit capacity, and packet buffering absorbs short traffic bursts before forwarding decisions are completed. Typical applications include 16-port Gigabit Ethernet switches, industrial network equipment, network-interface appliances, aggregation equipment, and embedded systems requiring multiple copper or fiber-linked Ethernet ports. The parallel uplink can connect the switched ports to a host processor, another switch, or a router, depending on the surrounding system architecture. PCB design must follow the manufacturer’s BGA land pattern, ball assignment, power, clock, SerDes, and decoupling requirements. Differential high-speed pairs need controlled impedance, uninterrupted reference planes, minimized stubs, and manufacturer-recommended spacing. Because the supplied excerpts do not include operating voltage, temperature range, pin list, or exact package dimensions, those values should be confirmed from the full manufacturer datasheet before release. This product record combines verified source links, procurement fields, interface facts, and design-focused context. The alternatives list remains intentionally limited because the supplied cross-reference search did not identify any verified pin-compatible replacement MPNs.

The verified manufacturer documentation describes a complete high-speed switch system combining a packet buffer, Media Access Controllers, address management, and a non-blocking switch controller. It supports the IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x specifications, including MAC control PAUSE-frame handling, making it suitable for structured networking equipment, gateway platforms, routers, switches, and industrial Ethernet systems. The part is identified by distributors as a 16-port Layer 2 Gigabit Ethernet switch with integrated SerDes, and one distributor lists the BCM5396IFBG from $45.6230 as of 2026-10-28. The BCM5396IFBG is a Broadcom Limited interface IC with an exact package designation and pinout not included in the supplied verified data. Consequently, package dimensions, pin names, electrical limits, clocking requirements, thermal ratings, and absolute maximum ratings are recorded as unavailable rather than estimated. Its integrated SerDes architecture can reduce external switching-component count in a Layer 2 design, while the non-blocking controller and packet buffer support high-throughput Ethernet aggregation. The IEEE 802.3x PAUSE-frame support is important when downstream devices cannot accept traffic at line rate, although exact buffering and flow-control thresholds must be confirmed from the manufacturer datasheet. This product page is intended as an engineering summary, not as a substitute for the complete Broadcom data sheet. It combines verified source information, commercial availability, application context, and strict data-quality markers to distinguish documented facts from values that still require confirmation before schematic capture, PCB layout, thermal analysis, or production release. The BCM5396IFBG should therefore be evaluated as a highly integrated switching solution for Gigabit Ethernet products where port density, integrated SerDes, Layer 2 management, and non-blocking switching are the primary design requirements.

The Broadcom BCM5396KFB is a 16-port Gigabit Ethernet switch integrated circuit with integrated SerDes, specified in a 256-pin FBGA package and a 16,000 Mbps switching capacity. It combines the packet buffer, Media Access Controllers, address management, and a non-blocking switch controller in one monolithic 0.13 µm CMOS device, providing a compact foundation for multiport Ethernet systems. A Gigabit Ethernet switch is a network-semiconductor device that receives Ethernet frames through multiple ports, maintains the required MAC and address information, and forwards traffic through an internal switching fabric. Ethernet switching belongs to networking and communications electronics, where throughput, port density, media interfaces, buffering, and frame handling determine whether a system can support simultaneous data flows without unnecessary contention. The BCM5396KFB's principal verified features include 16 Gigabit Ethernet ports, integrated SerDes, and a non-blocking switch controller. Its listed aggregate throughput is 16,000 Mbps. The Broadcom datasheet also states compliance with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x, including MAC-control PAUSE-frame support. These functions place the device in the family of Ethernet interface and switching semiconductors rather than a general-purpose microcontroller or standalone physical-layer transceiver. The monolithic 0.13 µm CMOS implementation consolidates packet buffering, MACs, address management, and switching control. That integration can reduce the number of external network components in a designed platform, although board-level operation still depends on power delivery, clocking, SerDes implementation, thermal conditions, magnetics or PHY integration, and validated firmware or driver support. The supplied distributor references classify the part as a 16-port layer-2 Gigabit switch with integrated SerDes. Typical equipment uses include 16-port managed Gigabit Ethernet switches, industrial Ethernet aggregation, network-interface appliances, telecom access equipment, and embedded systems that need multiple copper or fiber-facing ports. These uses are consistent with the verified 16-port architecture; exact supported media type, connector arrangement, electrical limits, and board implementation must be confirmed from the complete manufacturer datasheet before release. Engineers should preserve the manufacturer's ball map, power and decoupling layout, thermal design, and high-speed routing constraints. A 256-pin FBGA is demanding to route and inspect, so assembly yield, via-in-pad policy, solder-mask definition, and X-ray or AOI coverage should be reviewed early. This page separates verified facts from unavailable electrical details and avoids treating distributor classifications as substitutes for a complete pinout. This page consolidates distributor sourcing, datasheet references, design cautions, and strict drop-in-compatibility checks that are not available from a bare distributor listing. Because no verified substitute shares the exact BCM5396 footprint and electrical configuration, engineering review is required before any proposed replacement is approved.

The Broadcom BCM5396KFBG is a 16-port Gigabit Ethernet switch with integrated SerDes, provided in a 256-FBGA package measuring 17 x 17 mm. It combines packet buffering, Media Access Controllers, address management, and a non-blocking switch controller in one monolithic 0.13 µm CMOS device. The device uses an SPI interface for host configuration and supports the IEEE 802.3, 802.3u, 802.3ab, and 802.3x specifications identified in the manufacturer datasheet. An Ethernet switch is a network-semiconductor device that receives Ethernet frames on multiple ports and forwards them through a shared internal switching fabric. The BCM5396 family integrates 16 Gigabit Ethernet ports with physical-layer transceiver functions, allowing a board to implement a multi-port network interface without using a separate switch controller and sixteen external SerDes devices. The switch controller and packet-buffer architecture coordinate traffic transfer among ports. The most prominent functional characteristics are the 16 Gigabit Ethernet ports, integrated SerDes, non-blocking switch operation, and integrated packet buffer. The monolithic design also includes Media Access Controllers and address management. These features make the BCM5396 suited to compact networking equipment where port density, integration, and board area matter. The SPI host interface provides a control path for configuring switch operation and managing relevant networking parameters. Broadcom's manufacturer datasheet describes the BCM5396 as a highly integrated high-speed switch solution. It is implemented in 0.13 µm CMOS, combining the MACs, packet buffer, address-management logic, and switch controller rather than relying on discrete components for those functions. It complies with the IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x specifications, including support for MAC-control PAUSE frames. Exact clock, voltage, power, and temperature limits were not available in the supplied excerpts and require confirmation in the complete datasheet. Typical applications include industrial Ethernet switches, telecom access equipment, network-interface appliances, and multi-port embedded networking systems. In these systems, the 16 integrated ports can reduce component count and PCB routing demand compared with a design built from discrete Ethernet PHYs. Its low-power operating mode, noted in distributor product information, may be useful when port activity or traffic demand is limited. The SPI interface also makes the device suitable for systems whose supervising processor must initialize or supervise the switch. The primary design consideration is package complexity. A 256-FBGA device requires a fine-pitch PCB land pattern, careful escape routing, reliable power and ground distribution, and assembly capability suitable for large ball-grid arrays. Designers should also verify clock requirements, SerDes electrical characteristics, thermal performance, reset behavior, and supported PHY or media arrangements against the complete manufacturer datasheet before releasing layout or production files. This page consolidates verified distributor listings, the Broadcom manufacturer datasheet excerpt, package information, sourcing data, and application guidance. It also distinguishes documented BCM5396 capabilities from details that still require validation, helping engineers evaluate the device without mistaking incomplete distributor metadata for a complete electrical specification set.

The device is supplied in a 121-pin plastic ball grid array package for compact network-interface designs. An Ethernet PHY converts between a digital MAC-side interface and analog copper-cable signaling. The BCM5482A1KFB integrates two physical-layer channels, allowing one component to serve two Ethernet ports while reducing board area in IP phones, access equipment, industrial controllers, and other multiport systems. Its dual-port architecture can reduce the number of discrete PHY packages required on a board. The BCM5482A1KFB supports 10, 100, and 1000 Mb/s rates and is compatible with IEEE devices operating in half-duplex and full-duplex configurations. This broad rate support lets a product design accommodate legacy 10BASE-T and 100BASE-TX links while retaining Gigabit Ethernet capability. The integrated SerDes also connects the PHY channels to digital network processors or switching silicon. Clock timing can be adjusted to compensate for board-trace delays required by the RGMII specification. This feature is particularly useful when the PHY and MAC are separated by a routed interface or when propagation delay through a multilayer board would otherwise affect timing margins. The adjustment capability supports more practical placement of high-speed digital circuitry on space-constrained boards. Low-power operation is a central design benefit for dual-port PHYs because each active channel continuously performs line coding, signal conditioning, and cable diagnostics. The device is suited to IP phone uplinks, industrial networking equipment, customer-premises equipment, and embedded dual-Ethernet systems where package size, port density, and interface timing are important design constraints. For implementation, follow the Broadcom BCM5482 documentation for power sequencing, magnetic-component selection, termination, clock configuration, and the exact pin assignments. Preserve the recommended high-speed layout practices around the RGMII interface and place input, output, and decoupling connections according to the reference design to avoid signal-integrity degradation. This page combines the device’s dual-port Gigabit Ethernet capabilities with practical selection guidance, verified source links, interface considerations, and design guidance. It is designed to help engineers identify the correct operating conditions and board-level integration requirements before committing a BCM5482A1KFB-based Ethernet interface to production.

BCM55030SB01 - 10G EPON MDU Clock/Timing IC | Broadcom

The Broadcom Limited BCM55030SB01 is an application-specific clock and timing integrated circuit identified by distributor listings as a 10G EPON MDU device. It belongs to the Clock & Timing category within integrated circuits and is supplied in a surface-mount package designated by the SB01 ordering suffix. The verified source data identifies the component as an IC output device, but it does not publish the operating voltage, output frequency, timing tolerance, temperature range, or pin configuration needed for a complete electrical specification. An application-specific clock and timing IC is a specialized semiconductor that generates, distributes, or conditions clock signals within a defined equipment architecture. Unlike a generic oscillator, an application-specific timing device is optimized around a particular system or transceiver ecosystem. In an EPON MDU, clock and timing support can be required alongside burst-mode transmitters, receivers, serializers, and other line-access circuitry, where consistent clocking contributes to stable data throughput and low bit-error rates. The key verified identification for BCM55030SB01 is its association with a 10G EPON MDU application. That association is more useful than a generic category label because it indicates the intended equipment context in which Broadcom positioned the part. Distributor records classify it under Application Specific Clock/Timing, while other marketplace listings describe it as an IC Output and an application-specific timer. The Broadcom family also includes closely related BCM55030-series devices, but the supplied evidence does not establish their pin compatibility or parameter differences with this exact suffix. Because no manufacturer datasheet parameters or verified pricing were returned in the source data, electrical values such as supply voltage, output frequency range, jitter, reference-input requirements, and operating temperature must be confirmed before design release. Likewise, the physical package dimensions and pad assignment remain unverified. The package diagram is therefore represented by the default library graphic rather than an invented package-specific drawing, and the pinout is intentionally omitted instead of presenting unverified pin names. Typical engineering use is limited to designs already qualified around the Broadcom 10G EPON MDU signal chain, including line-card, aggregation, and access-network equipment. For new designs, engineers should request the controlled Broadcom datasheet and obtain a sample of BCM55030SB01 to confirm reference requirements, output behavior, decoupling, layout constraints, and production availability. Distributor listings report availability and sourcing options, but lead time, lifecycle status, and unit pricing require a current quotation. The practical design consideration is that this part should not be treated as a generic clock source or selected by package name alone. Its suitability depends on compatibility with the associated EPON MDU clock architecture, reference source, and board-level timing budget. Procurement should also confirm whether BCM55030SB01 is an active orderable configuration or a legacy ordering code within the broader BCM55030 family. This page consolidates the verified distributor identity, application classification, source traceability, and engineering-selection guidance for BCM55030SB01. It also separates confirmed information from unavailable electrical, mechanical, pricing, and lifecycle data, helping buyers request the correct manufacturer documentation before committing the part to a production BOM.

It is categorized as an integrated semiconductor device intended for embedded connectivity and control systems. The exact electrical ratings, processor configuration, memory capacity, transceiver characteristics, pin count, package dimensions, and environmental limits are not stated in the available manufacturer-facing references for this ordering code, so those values should be confirmed against the Broadcom product documentation before design release. An SoC combines multiple functional blocks on one semiconductor device. In embedded networking equipment, an SoC may integrate a processor, memory interfaces, communications controllers, and supporting peripherals to reduce component count and simplify a board design. The BCM55030SF01 designation specifically appears in connection with BCM55030 and BCM54640, indicating a specific Broadcom device ordering code rather than a generic discrete component. Its system-level integration can help designers standardize platforms across gateway, access, and industrial networking products, but the exact interface set must be checked for each revision. The BCM55030SF01 is listed by Broadcom as a System on Chip (SOC) IC. Distributor catalog records also classify the part as an embedded SoC and identify Broadcom as the manufacturer. This classification is the key technical fact available for initial component selection. Before assigning this device to a PCB, engineers should verify the package drawing, pin assignment, power architecture, required clocking, boot interface, Ethernet or other network interfaces, and recommended external components in the appropriate Broadcom datasheet. Typical engineering uses include embedded network appliances, access equipment, industrial controllers, and communication systems that require a highly integrated Broadcom platform. The device may be considered when a design needs the BCM55030 and BCM54640 feature combination in one ordering code. Suitability depends on matching the available interface set, performance requirements, software support, operating-temperature range, and lifecycle expectations to the target product. For PCB design, preserve the package-specific land pattern, provide the required power and decoupling networks, and follow the reference clock and reset guidance in the manufacturer documentation. For software, verify the supported boot flow, firmware image format, device-tree or board-support-package requirements, and peripheral pin multiplexing. Do not infer register compatibility from the BCM55030 or BCM54640 names alone; use the exact BCM55030SF01 documentation for the production design. This page organizes the confirmed Broadcom identity, the BCM55030 plus BCM54640 device description, catalog sources, commercial request path, and design questions engineers should resolve. It is intended to support early sourcing and engineering review while directing final footprint, electrical, and qualification decisions to the exact manufacturer documentation.

The Broadcom BCM55524SD02 is a BCM55524 chipset packaged as a system-on-chip (SoC) integrated circuit for network controller and processor applications. The part is identified in manufacturer-related channel listings under the exact ordering code BCM55524SD02, with Broadcom classified as a network controller and processor IC supplier. Its physical package, pin arrangement, electrical ratings, and operating limits are not stated in the available product records. A system-on-chip is an integrated circuit that combines multiple functional blocks within one semiconductor device. The SoC category sits within integrated circuits and can include processor, controller, memory-interface, communications, and peripheral functions. Unlike a discrete controller surrounded by numerous external devices, an SoC centralizes those functions into a single package, which can simplify board partitioning and reduce the number of interconnects required by a system. The BCM55524SD02 is specifically associated with the BCM55524 chipset identity. That chipset name distinguishes it from unrelated Broadcom connectivity processors and is the primary basis for locating an appropriate datasheet or technical reference. Because the accessible records do not enumerate CPU type, memory configuration, interface set, clocking, I/O voltage, or thermal limits, engineers should not infer those capabilities from the Broadcom product name alone. Broadcom network-controller SoCs are commonly evaluated for connected equipment that requires local packet handling, peripheral connectivity, or system-level control. A controller implementation may use the SoC alongside Ethernet PHYs, memory, flash storage, clock sources, power regulators, and isolation or protection components. The exact companion devices must be selected from the controller's documented interface requirements rather than from generic protocol similarity. The same-family BCM47083SL01 appears in the XAIPART product catalog and can be considered as an adjacent Broadcom connectivity-controller option during architecture reviews. It is not listed here as a drop-in substitute because no pin-level or parametric cross-reference establishes package, pinout, firmware, memory, or interface compatibility with BCM55524SD02. A sound design process starts with the exact Broadcom technical documentation for BCM55524SD02, then maps power, clocks, boot media, memory interfaces, networking interfaces, and exposed I/O onto the PCB. Verify the package drawing and pin table before layout, and confirm schematic signal levels, reset behavior, boot configuration, and thermal conditions with the manufacturer before release. This product record combines exact-part identification, current channel availability references, related Broadcom ecosystem options, and a verification checklist for design-in decisions. It distinguishes the BCM55524SD02 from unsupported replacements and helps engineers identify the technical documents, interfaces, and qualification details that must be reviewed before schematic approval or PCB release.

BCM56524B0KFSBG - 24-Port 108 Gbps Switch Fabric | Broadcom

The Broadcom BCM56524B0KFSBG is a 24-port Gigabit Ethernet switch fabric IC delivering 108 Gbps of aggregate switching bandwidth in a single integrated device, supplied in a BG (ball-grid) package intended for high-density enterprise and SMB switching platforms. It combines PHY-less GbE MACs, a shared-memory packet buffer, and an embedded management CPU to deliver wire-speed switching for layer-2 and basic layer-3 enterprise workloads. An Ethernet switch fabric (also called a switch ASIC or switching chipset) is the silicon heart of a managed network switch that moves packets between physical Ethernet ports and uplinks at line rate. Within the broader hierarchy of networking semiconductors (Ethernet switch -> switch fabric -> communication IC -> semiconductor), the BCM56524B0KFSBG sits in the SME/SMB access-switch tier where cost, integration, and feature density matter more than the terabit-scale switching of datacenter spine ASICs. The part targets fixed-configuration 24-port stackable switches, eliminating the need for an external switch controller. Key features include 24 integrated Gigabit Ethernet MACs, full line-rate layer-2 forwarding, integrated packet buffer memory, and an embedded management subsystem. Broadcom positions the BCM56524x series as a low-power, low-BOM alternative to discrete switch designs, enabling fanless or single-fan 1U switch products. Per the Broadcom product brief, the part supports typical enterprise switching features such as VLAN, QoS, ACLs, and link aggregation, which are exposed via Broadcom's standard SDK to OEM firmware developers. Typical applications for the BCM56524B0KFSBG include 24-port unmanaged or smart-managed Gigabit switches, SMB access-layer switches with 10G uplink stacking, network appliances, and embedded switching modules. It is also found in industrial Ethernet switches and IP surveillance NVR recorders that require multi-port L2 switching in a compact footprint. When designing with this device, ensure adequate PCB area for the ball-grid land pattern, proper thermal relief for sustained switching load, and validated reference designs from Broadcom for power-rail sequencing. Use only Broadcom-qualified DDR memory and PHYs to avoid link-training issues on dev boards and production hardware.
