BCM5396KFB Übersicht
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.

Typische Anwendungen
BCM5396KFB ist geeignet für 6 Anwendungs: Managed 16-Port Gigabit Ethernet Switch, Industrial Ethernet Aggregation, Telecom Access Equipment, Network Interface Appliance, Embedded Multiport Network Controller, Lab Network Test Equipment.
Managed 16-Port Gigabit Ethernet Switch
The BCM5396KFB fits a managed layer-2 switch platform that needs 16 Gigabit Ethernet ports and 16,000 Mbps aggregate capacity. Its verified integration of MACs, address management, packet buffering, and a non-blocking switch controller places the core forwarding functions in one 0.13 µm CMOS device. A board designer would add the required media interfaces, management processor or control interface, power regulation, and thermal implementation around the 256-pin FBGA. The benefit is architectural consolidation, but firmware, PHY or magnetics integration, and exact port electrical limits must be verified against the full Broadcom datasheet before release.
Empfohlen
Industrial Ethernet Aggregation
The BCM5396KFB is suitable for an industrial aggregation platform requiring a high concentration of Gigabit Ethernet ports in a surface-mount device. Its 16-port layer-2 architecture and integrated SerDes can support centralized switching where equipment links converge onto a common network fabric. The design must still address industrial temperature requirements, isolation, surge protection, grounding, and connector strategy, because those requirements are not numerically documented in the supplied data. The verified 16,000 Mbps capacity provides a clear sizing anchor, while PCB thermal design must account for the large 256-pin FBGA and its multilayer routing demands.
Empfohlen
Telecom Access Equipment
BCM5396KFB can form the switching core of telecom access or network-interface equipment where multiple Gigabit Ethernet links need coordinated frame forwarding. Its integrated Media Access Controllers, address management, packet buffer, and non-blocking controller reduce the number of discrete network functions specified for the monolithic device. IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x support provides a verified standards baseline, including MAC-control PAUSE handling. Deployment still requires carrier-grade temperature, reliability, regulatory, and line-interface requirements that are not present in the supplied records.
Empfohlen
Network Interface Appliance
The BCM5396KFB is applicable to a dedicated network appliance that terminates or aggregates up to 16 Gigabit Ethernet connections. By integrating the switch functions on one CMOS device, it can simplify the topology compared with separately assembled switching blocks, while the verified non-blocking controller and 16,000 Mbps aggregate figure support concurrent traffic analysis. The implementation must define PHY, copper-magnetics, optical-interface, management-plane, clock, and reset architecture independently. Because the supplied data does not expose pin assignments or power limits, hardware engineering must defer footprint release to the manufacturer package drawings.
Empfohlen
Embedded Multiport Network Controller
BCM5396KFB can serve as the dedicated multiport forwarding element in an embedded network appliance when the host processor should not perform individual Ethernet switching. The device consolidates packet buffering, MACs, address management, and switch control into a 0.13 µm CMOS implementation, leaving the host to manage higher-level services. This role requires careful partitioning of reset, configuration, status, firmware, and traffic-management interfaces; none of those electrical or software details are verified here. The main hardware benefit is a dedicated 16-port fabric, offset by demanding FBGA routing and a larger verification scope.
Empfohlen
Lab Network Test Equipment
The BCM5396KFB can be evaluated for laboratory Ethernet aggregation, traffic-generation, and protocol-analysis equipment that requires many simultaneous Gigabit links. Its verified 16-port capacity and non-blocking switch controller provide a useful basis for repeatable test-system experiments. Instrumentation designs must add precision timing, synchronization, capture, trigger, and host interfaces not specified by the device data. Engineers should treat the 256-pin FBGA as a controlled high-density assembly and plan power integrity, thermal monitoring, boundary scan, and fixture access before committing to a dense test board.

Designhinweise
Do not release the 256-pin FBGA layout from a generic package image. Obtain the Broadcom ball map, recommended stack-up, escape geometry, and via rules, then cross-check every power, ground, signal, and exposed-function assignment against the complete datasheet. The verified package description establishes only the 256-pin FBGA format; it does not provide authoritative pin numbering for this output.
Plan a layered power-distribution network around the package once the manufacturer identifies core, analog, I/O, and SerDes supply domains and their voltage values. Use the datasheet's decoupling and topology requirements directly; the supplied data does not state supply voltage, current, tolerance, sequencing, or ramp limits. Avoid inventing capacitor values from generic FBGA guidance and validate power integrity across startup, traffic, and temperature conditions.
Treat heat spreading and copper connectivity as board-design requirements because the verified 256-pin FBGA has many package connections but no verified power or thermal data. Estimated thermal performance cannot be produced without package dimensions, board construction, copper area, airflow, and electrical dissipation. After schematic release, calculate worst-case dissipation from actual rail currents and validate junction temperature using the manufacturer's thermal model or test data.
Compliance-Informationen
The supplied records do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x are interface standards cited by the Broadcom datasheet, not product-level environmental compliance certifications.
