• Enterprise campus core and distribution layers
• Service provider edge aggregation networks

Procurement Notes

Verify the specific suffix 'B1' against the manufacturer's official documentation to confirm the exact temperature range and package variant. Ensure compatibility with the intended board design regarding pinout and power requirements. Request original manufacturer test reports or datasheets to validate authenticity before procurement.

Selection Notes

Select this component when a balance of high port density and moderate throughput is required for access or aggregation layers. Compare against the BCM56450 series variants to determine if higher bandwidth options like the BCM56457 are necessary for future scalability. Evaluate thermal management solutions suitable for the FBGA package in the target enclosure.
