Procurement Notes

This component is officially listed as End-of-Life (EOL) and no longer manufactured by Skyworks Solutions Inc. Distributors such as Mouser indicate that the product is not available for sale in many regions. Verification of stock status should be conducted directly with authorized suppliers or through official Product Change Notifications (PCN) to confirm availability and obsolescence timelines before procurement planning.

Selection Notes

Designers must account for the discontinued status when selecting this part. The SI52111-A2-GM2 is a related variant within the same series but may differ in specific ordering suffixes and functional configurations. Selection requires careful review of the datasheet to ensure compatibility with existing PCIe Gen 1 requirements and pinout constraints, particularly regarding the TDFN-10 package dimensions.

Part Context

The SI52111-B12-GM2 belongs to the SI52111 family of clock generators designed specifically for PCI Express applications. This series supports various PCIe generations and output configurations. The B12 suffix denotes specific electrical and packaging characteristics unique to this model within the broader Skyworks timing portfolio.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Due to the EOL status, engineers should consult Skyworks Solutions for recommended alternatives or cross-reference with similar PCIe clock generators from other manufacturers, ensuring electrical and mechanical compatibility.
