Procurement Notes

This component is officially discontinued by Broadcom Limited. Procurement is restricted to remaining stock from authorized distributors or secondary market suppliers. Verify authenticity and condition carefully, as availability is limited and subject to existing inventory levels. No new production units are available through standard manufacturing channels.

Selection Notes

Engineers should evaluate alternative Broadcom Ethernet ICs within the same family that remain in active production. Consider functional compatibility regarding multi-layer switching and IEEE 1588 requirements when selecting a replacement. Ensure the substitute component matches the required package type and interface specifications for seamless integration into existing designs.

Part Context

The BCM56540XB0KFSBG is part of Broadcom's broader portfolio of Ethernet switching integrated circuits. It serves as a specialized solution for telecom interfaces, emphasizing multi-layer processing and time-sensitive networking features. As an EOL item, it represents a previous generation of Broadcom's networking silicon designed for high-performance communication applications.

Replacement Considerations

Consult Broadcom's official Product Change Notification (PCN) documents for recommended alternatives. Identify current-generation Ethernet ICs that maintain similar multi-layer switching and IEEE 1588 functionality. Verify pinout and software compatibility before transitioning to a new part number.
