BCM54640B0KFBG

Overview

The BCM54640B0KFBG is a single-port Gigabit Ethernet PHY manufactured by Broadcom Limited. It supports 10BASE-T, 100BASE-TX, and 1000BASE-T standards over copper cabling. The device integrates an on-chip low-voltage regulator and provides multiple MAC interface options including GMII, RGMII, RTBI, and MII. It operates within a voltage range of 3.3V and utilizes a BGA-135 package for surface-mount installation.

Feature Summary

Supports full-duplex and half-duplex operation across 10/100/1000 Mbps speeds
Includes automatic MDI/MDIX crossover correction at all data rates
Features integrated cable-plant diagnostics and link quality indication

Applications

Embedded network interfaces in industrial control systems
Network switches and routers requiring compact form factors
Consumer electronics with integrated Gigabit Ethernet connectivity

Procurement Notes

Verify the specific suffix KFBG against the official datasheet to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the BGA-135 configuration. Check for moisture sensitivity levels and reflow soldering requirements prior to assembly.

Selection Notes

Select this component when a single-port Gigabit solution with integrated regulators is required. Compare against BCM5461 series variants if different packaging or temperature grades are needed. Verify MAC interface support matches the host processor's available ports.

Part Context

This part belongs to the Broadcom BCM5461 family of Gigabit Ethernet transceivers. It shares architectural similarities with other members like the BCM5461SA1 series but differs in specific pinouts and package configurations. The B0 suffix typically denotes a specific manufacturing revision or binning category within the product line.

Replacement Considerations

Direct replacements include BCM5461SA1IPFG and BCM5461SA1KPFG. Verify pin-to-pin compatibility and electrical specifications before substitution. Alternative packages may require schematic and layout modifications.
