Procurement Notes

Verify the manufacturer origin carefully, as Flip Electronics acts as a distributor rather than the original semiconductor manufacturer. Confirm that the part number matches the specific Broadcom silicon revision and ensure compliance with RoHS standards before integration into final designs.

Selection Notes

Select this component when requiring a fixed port configuration of 24 GE and 4x HG interfaces within a single integrated circuit. It is suitable for designs prioritizing space efficiency and standardized gigabit throughput over customizable port counts found in other switch families.

Part Context

This part belongs to the Broadcom BCM563xx series of Gigabit Ethernet switches. It is functionally related to variants like the BCM56320B1KFSBG but distinguishes itself through its specific port count and package configuration tailored for high-port-density telecom applications.

Replacement Considerations

Consult official Broadcom documentation for direct pin-to-pin replacements or functional equivalents within the BCM563xx family. Verify compatibility with existing board layouts and firmware requirements when substituting with similar switch ICs.
