BCM5395SIPBG - 5-Port Gigabit Ethernet Switch | Broadcom
MPN: BCM5395SIPBG ✓ ActiveBCM5395SIPBG Overview
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.

Typical Applications
BCM5395SIPBG is suitable for 6 applications: Compact Business Ethernet Switch, Industrial Ethernet Gateway, Embedded Network Concentrator, Networked Storage and Printer Adapter, Five-Port Network Interface Module, Telecom and Network Equipment Interface.
Compact Business Ethernet Switch
BCM5395SIPBG fits a compact business Ethernet switch that needs five local Gigabit connections rather than a collection of unrelated Ethernet interfaces. Four ports can serve workstations, access points, printers, or storage devices while a fifth port provides an uplink, subject to the product architecture and management configuration. Supporting 1000 Mbps on every port gives each endpoint dedicated 1 GbE-class bandwidth. The integrated five-PHY arrangement can also reduce the number of separate copper-network transceiver packages, while the packet buffer consolidates frame storage in the switching IC. The design still needs appropriate magnetic or isolation circuitry, host-interface support, reference clocking, power distribution, and layout that follows the manufacturer reference design.
Recommended
Industrial Ethernet Gateway
The five-port configuration of BCM5395SIPBG is useful for an industrial Ethernet gateway that must aggregate several local devices while preserving a connection to an upstream network. Each port can operate at up to 1000 Mbps, allowing the gateway to avoid a shared 100 Mbps bottleneck when the connected equipment and network infrastructure support Gigabit Ethernet. Its integrated PHYs and packet buffer simplify the switching side of the design, but the gateway processor still requires a compatible host interface and firmware. Before using the device in industrial equipment, confirm operating temperature, electrical limits, PHY media, clocking, reset behavior, isolation requirements, and qualification status directly from the Broadcom documentation.
Recommended
Embedded Network Concentrator
BCM5395SIPBG can serve as the five-port switching element in an embedded network concentrator that connects sensors, controllers, service nodes, and an uplink. The five integrated PHYs provide one Gigabit Ethernet physical layer per port, while the integrated packet buffer supports local switching without an external frame-memory component immediately adjacent to the switching core. This arrangement is appropriate when the embedded host has a compatible interface to the Broadcom switch and can manage the required Ethernet functions. Keep analog PHY routing separate from digital host signals, provide stable clocking and decoupling, and use the manufacturer's recommended network magnetics or other specified physical-layer network components.
Recommended
Networked Storage and Printer Adapter
A multi-port adapter built around BCM5395SIPBG can provide shared Gigabit Ethernet access for storage appliances, printers, scanners, or other networked peripherals. Five 1000 Mbps ports allow multiple devices to operate concurrently without sharing one external uplink for the entire group, provided the host-side interface and upstream link support the intended traffic pattern. The integrated packet buffer helps the switching IC handle frames locally, while five integrated PHYs reduce the physical-layer component count. A successful implementation still depends on validating media support, frame handling, host protocol support, thermal performance, and the exact package. Follow the manufacturer reference schematic for magnetics, termination, power, and clock arrangements.
Recommended
Five-Port Network Interface Module
BCM5395SIPBG is appropriate for a dedicated five-port network-interface module intended to bridge an embedded controller or modular system into multiple Ethernet links. The switch architecture provides five 1000 Mbps ports and an integrated packet buffer, while the integrated PHYs reduce the number of separate PHY packages needed for a copper-only design. The host processor must communicate through the exact supported interface and configure the switch appropriately, so engineers should review timing, register behavior, firmware requirements, and initialization sequence in the Broadcom documentation. Layout effort should focus on controlled-impedance routing, uninterrupted reference planes, careful magnetic-component placement, and the manufacturer-specified package and exposed-pad footprint.
Recommended
Telecom and Network Equipment Interface
BCM5395SIPBG can support a compact telecom or network-equipment interface that requires several internal 1000 Mbps Ethernet connections. The five integrated PHYs allow local control traffic, service traffic, and management traffic to terminate at a central switching block, while the integrated packet buffer supports efficient local frame handling. This use is technically attractive where board area and component count are important, but the host interface must match the application processor or switch-management controller. Confirm exact protocol support, PHY characteristics, timing, package geometry, and environmental limits before using BCM5395SIPBG in telecom-grade equipment. The PCB should implement the reference power, clock, magnetics, and signal-routing scheme without substituting unverified network components.

Design Notes
Separate each 1000 Mbps PHY channel from host-interface and switching-core routing, and maintain a continuous ground reference beneath the package and high-speed paths. Place Ethernet magnetics or other required network-interface components close to their associated PHY pins. Use the manufacturer reference layout and PCB stack-up when defining controlled-impedance dimensions rather than applying generic Ethernet routing rules to an undocumented package.
Confirm the BCM5395 supply range, core and I/O voltage requirements, tolerance, sequencing, and exposed-pad connection from the manufacturer datasheet before assigning power rails. Provide low-impedance decoupling at the package pins and use a quiet, stable source for the switching core and PHYs. Check junction-temperature rise at the highest expected traffic because sustained switching activity can increase dissipation even when the host-side traffic load is moderate.
Treat reference clocks, reset timing, host-interface signals, and PHY channels as separate constraint groups. Maintain short return paths, avoid stubs, and place clock-decoupling components near their loads. Validate magnetics selection, termination, pair geometry, and isolation against the supported media and reference design. Simulation and edge-rate measurements should be based on the actual host interface and PCB stack-up rather than treating every signal in the design as the same Ethernet channel.
