Analog Switches - Special Purpose Procurement Notes

Verify the component status as active with Broadcom Limited. Confirm the specific suffix CA80BC matches the required thermal and packaging specifications. Ensure compatibility with the FCBGA-676 footprint during procurement planning. Check for moisture sensitivity level requirements prior to assembly handling.

Analog Switches - Special Purpose Selection Notes

Select this model when a 48-lane, 12-port configuration is required for Gen 3 PCIe architectures. Consider the 40nm process node for power efficiency relative to older generations. Evaluate the need for visionPAK debug tools if complex traffic patterns or peer-to-peer scenarios are anticipated in the design.

Analog Switches - Special Purpose Part Context

This part belongs to the PEX 8748 series, which focuses on fan-out, aggregation, and peer-to-peer traffic patterns. It serves as a core connectivity solution within Broadcom's portfolio for data center and enterprise infrastructure, bridging host processors with peripheral endpoints.

Analog Switches - Special Purpose Replacement Considerations

Public documentation lists the PEX8734-AB80BI G as a manufacturer-recommended alternative for related legacy parts like the PEX8606. Verify lane count and port availability differences before substituting, as direct pin-to-pin equivalence is not explicitly confirmed for all variants in the provided source material.
