Procurement Notes

Verify the specific suffix 'GMR' against official Skyworks documentation to confirm tape-and-reel packaging and exact electrical tolerances. Confirm end-of-life status or obsolescence notices prior to procurement, as availability may be restricted. Ensure compatibility with existing PCB footprints and thermal management requirements during sourcing.

Selection Notes

Select this component when a four-output clock solution is required for PCIe Gen1/2/3 compliance. Verify that the 3.3 V supply rail matches the target design constraints. Compare jitter specifications and output swing levels against downstream receiver requirements to ensure signal integrity standards are met without additional buffering.

Part Context

This part belongs to the SI52144 series of clock generators. It shares functional similarities with other Skyworks PCIe clock solutions but is distinguished by its specific four-output configuration and Gen1/2/3 support capabilities. The 'A14A' designation typically indicates specific pinout or electrical characteristics within the family.
