Procurement Notes

This component is officially classified as End-of-Life by the manufacturer. A Product Change Notification regarding discontinuation was issued on October 25, 2024. Verification of current availability should focus on surplus or secondary market sources rather than direct manufacturing orders. Buyers must confirm the specific revision level and packaging integrity due to the discontinued status.

Selection Notes

Engineers selecting this part should verify compatibility with existing StrataXGS ecosystem requirements. The design must account for the 24GE plus 4x10GE port configuration. Since the part is obsolete, alternative solutions within the same Broadcom family or newer generations should be evaluated for long-term supply chain stability and pin-to-pin compatibility.

Part Context

The BCM56440XB0KFSBLG is a specific variant of the Broadcom StrataXGS BCM56440 series. This series targets operators seeking to upgrade mobile backhaul networks. The XB suffix typically denotes specific package or speed binning variations within the broader BCM56440 product line, tailored for high-performance telecom interfaces.

Replacement Considerations

Public documentation confirms the BCM56440XB0IFSBLG as a related variant within the same discontinuation notification. No other direct substitute part numbers are verified in the provided source material. Designers should consult Broadcom's official obsolescence notices for recommended next-generation replacements.
