Procurement Notes

Verify the exact suffix IFSBLG against official Broadcom documentation to confirm pinout and thermal specifications. Confirm availability status as supply conditions may vary. Ensure compatibility with existing PCB footprints and power delivery networks before integration. Request latest datasheets for any revisions or errata that might impact design implementation.

Selection Notes

Select this component when a balance of 24x1G and 4x10G ports is required for aggregated uplinks. Evaluate thermal requirements associated with the FBGA package in the target enclosure. Compare against alternative Broadcom series for specific feature sets like advanced telemetry or specialized routing protocols if needed.

Part Context

This part belongs to the Broadcom BCM55440 family of Ethernet switches. The family is known for providing robust switching fabrics for mid-range networking devices. The specific model variant indicates the package type and temperature range, distinguishing it from other members of the same functional family with different interface counts or packaging options.

Replacement Considerations

Check for direct cross-references within the BCM55440 series. Verify pin-to-pin compatibility with previous generation Broadcom switches if upgrading legacy designs. Ensure software drivers and management tools are compatible with the replacement silicon.
