Product Overview
The BCM54640EB2IFBG is Broadcom quad‑port gigabit Ethernet PHY transceiver IC. Built on low‑voltage CMOS process, integrates four independent 10/100/1000BASE‑T PHY channels with DSP noise suppression. Supports GMII, RGMII, SGMII, QSGMII MAC interface. Industrial grade -40°C~+85°C. This device is EOL discontinued, only surplus stock available for existing maintenance projects, not recommended for new‑design.
Core Advantages
Quad‑Port High‑Density Integration
Four complete gigabit PHY channels on single chip, reduce PCB footprint, BOM cost and layout complexity for multi‑port network hardware.
EEE Low‑Power Design
Complies with Energy‑Efficient Ethernet standard, dynamically adjust power consumption according to network traffic load.
DSP Enhanced Signal Performance
Adaptive equalization, echo & crosstalk cancellation, stable gigabit transmission over Cat5 UTP twisted‑pair cables.
Industrial‑Grade Wide Temperature
-40°C to +85°C operating range, suitable for industrial control and telecommunication harsh‑environment equipment.

Frequently Asked Questions
Q1: What does suffix “EB2IFBG” stand for?
A: “EB2” = chip revision; “I” = industrial temperature grade (-40℃~+85℃); “F” = 256‑Ball FBGA package; “B” = internal configuration; “G” = lead‑free RoHS compliant.
Q2: What is the difference between industrial‑grade and commercial‑grade BCM54640?
A: Commercial version removes suffix “I”, operating range 0℃~+70℃. They share identical FBGA footprint. Do not substitute commercial parts for industrial wide‑temperature projects.
Q3: How many Ethernet ports does BCM54640EB2IFBG support?
A: Quad‑port, four independent 10/100/1000BASE‑T gigabit PHY channels integrated in one chip.
Q4: What are the differences among GMII, RGMII, SGMII, QSGMII?
A: GMII/RGMII are parallel MAC interfaces. SGMII is serial for single PHY. QSGMII carries four PHY signals over one differential lane, saving PCB traces for quad‑PHY layout.
Q5: Is BCM54640EB2IFBG an EOL discontinued component?
A: Yes, this device is end‑of‑life. Only surplus stock available on market with potential refurbished risk. Only for legacy equipment maintenance, not allowed for new‑product design.
Q6: What are recommended alternative parts?
A: Suggest BCM54641, BCM5481x series for new projects. Function‑equivalent upgrade, not pin‑to‑pin compatible, hardware modification is mandatory.
Q7: Can I replace it with other brand quad‑port gigabit PHY?
A: Different‑brand PHYs are not pin‑compatible. Only other BCM54640‑series parts share same package, full validation is still required before replacement.
Q8: Where can I get datasheet and BGA footprint?
A: Full official datasheet requires Broadcom authorization. Request pin definition, CAD library and bulk quotation through our inquiry form.
