Specialized Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct channels. Confirm that the received units match the specific PM8564B-FEI designation and packaging requirements. Ensure handling procedures adhere to the specified MSL 4 guidelines to prevent moisture-induced damage during assembly. Review current Product Change Notifications for any recent updates to labeling or packing configurations.

Specialized Selection Notes

Select this component when a dedicated PCIe fan-out switch solution is required within the Switchtec portfolio. Compare against other models in the series based on lane count and port configuration needs. Ensure the BBGA-1311 package footprint aligns with the target PCB design constraints. Verify compatibility with the intended PCIe generation and system power delivery specifications before finalizing the bill of materials.

Specialized Part Context

This part belongs to the Microchip Switchtec family of PCIe switches, which provides scalable connectivity solutions for enterprise and data center environments. The PM8564B variant specifically addresses fan-out requirements using the PFX-L architecture. It complements other members of the family such as the PM8535B and PM8536B, offering distinct lane and port configurations to suit various system bandwidth demands.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other Switchtec models like the PM8535B-FEI or PM8536B-FEI only if their specific lane and port counts align with the design requirements. Any substitution requires rigorous validation of pinout compatibility and firmware support.
