BCM5395MIPBG - 5-Port Ethernet Switch | Broadcom
MPN： BCM5395MIPBG ✓ 啟用中BCM5395MIPBG 概覽
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.

典型應用
BCM5395MIPBG 適用於 6 應用s: Industrial Ethernet Gateway, Embedded Network Appliance, Access Point and Gateway Controller, Network Interface Controller, Communication Equipment, Industrial Sensor and Controller Hub.
Industrial Ethernet Gateway
The BCM5395MIPBG fits an industrial gateway that must consolidate five local Gigabit Ethernet links into a single host processor. Its five integrated PHYs reduce the number of discrete Ethernet controllers required on the board, while RGMII provides a compact connection to the host. Non-volatile configuration storage preserves port setup across power cycles, and interrupt generation supports event-driven handling of link and administrative activity. Before production release, verify the specified temperature range, electrical limits, isolation strategy, clock sources, and reset behavior against the complete Broadcom documentation.
推薦
Embedded Network Appliance
A compact network appliance can use the BCM5395MIPBG to provide five integrated Gigabit Ethernet ports without assigning a separate PHY to each copper connection. The integrated switching resource and packet buffer suit devices that bridge or route traffic locally, while MII, GMII, RGMII, and RvMII provide several host-interface choices. RGMII is particularly useful when connector count is more important than a legacy parallel interface. Layout work should preserve the required differential-pair geometry, magnetics isolation, reference-clock routing, and decoupling arrangement specified for the device.
推薦
Access Point and Gateway Controller
The BCM5395MIPBG is appropriate for access-point or gateway hardware where several Ethernet-facing ports must converge on one embedded processor. Five integrated PHYs allow the board to support multiple wired clients, and the available GMII, RGMII, MII, and RvMII interfaces allow the host connection to be matched to the system architecture. Interrupt generation avoids constant status polling, while non-volatile configuration supports repeatable startup behavior. Designers should confirm clock tolerances, reset sequencing, thermal margins, and all package assignments before schematic release.
推薦
Network Interface Controller
A network interface controller can use the BCM5395MIPBG when it requires multiple physical Ethernet connections and local frame switching rather than a single-port interface. Five integrated PHYs and an integrated packet buffer provide a consolidated hardware foundation, while the selectable parallel host interfaces support different processor and controller configurations. Non-volatile storage can retain operational settings, and interrupts let firmware respond to link or port events. Firmware development should follow the documented register initialization and host-interface timing requirements rather than treating the device as a generic plug-compatible PHY.
推薦
Communication Equipment
The BCM5395MIPBG supports communication equipment that needs several isolated copper-facing Ethernet ports and a single internal network engine. Its integrated PHYs reduce board component count, and the five-port switching function can support local traffic management between attached systems. RGMII offers a practical option for systems with limited connector resources, while MII and GMII remain relevant for designs using established parallel-interface layouts. Engineers must validate EMC, surge, magnetics, grounding, and isolation requirements separately for each deployed port because the switch IC does not remove the need for compliant external network hardware.
推薦
Industrial Sensor and Controller Hub
The BCM5395MIPBG can serve as the Ethernet aggregation component in a controller hub that connects sensors, service tools, and supervisory systems over Gigabit Ethernet. Five integrated PHYs simplify multiport wiring, and non-volatile configuration allows repeatable restoration of operational parameters. Host interrupts provide event notification for link state or administrative events, while RGMII can reduce host pin usage in a compact controller design. Product qualification should account for the controller’s environmental range, cable transients, isolation barriers, power-loss behavior, and the number of ports that must operate simultaneously.

設計說明
Route every Ethernet differential pair as a controlled-impedance pair with continuous reference planes and minimal stubs. Place the PHY-side network magnetics and termination network close to the corresponding connector or PHY interface, and keep high-current switching nodes away from clock, RGMII, GMII, and MII routing. Follow the manufacturer’s reference layout for ball escape, supply distribution, and decoupling because an FBGA package provides little tolerance for incorrect escape routing.
Partition supplies according to the manufacturer’s core, analog, and digital requirements, and place the specified bulk and high-frequency capacitors at their designated power balls. Validate startup sequencing, current transients, and power-supply headroom for all five PHYs operating simultaneously. Estimated thermal and dissipation calculations should use the actual input voltage, total port current, package thermal data, and board copper area; no numerical thermal rating should be inferred from the general FBGA designation.
Pay particular attention to reference-clock quality and host-interface timing. Keep MII, GMII, RGMII, and RvMII signals over continuous return paths, and avoid crossing split power planes or high-current paths. Determine whether the host interface requires source-synchronous timing adjustments through the PHY registers, and validate edge rate, skew, loading, and reset release against the final routing rather than only at the schematic level.
Do not treat a related BCM5395 order code as a drop-in replacement without comparing every package ball, supply rail, clock input, reset function, host-interface mapping, and initialization register. Non-volatile configuration can preserve settings that differ between otherwise similar devices, so include stored-configuration behavior in the substitution review. Also avoid using the component listing as a substitute for the complete electrical, timing, environmental, and package documentation.
合規資訊
