Procurement Notes

Verify availability status as this component may be subject to end-of-life notices or limited stock conditions. Confirm RoHS compliance details through official datasheets before procurement. Ensure ordering suffixes match specific packaging requirements such as reel quantities for automated assembly processes.

Selection Notes

Select this model when a single differential or single-ended output is required for PCIe applications. Compare against the SI52111-A2 variant if spread spectrum functionality is needed. Verify that the 100 MHz maximum output frequency meets system requirements. Check compatibility with available crystal oscillators for the 25 MHz input reference.

Part Context

This part is part of the SI52111 family of clock generators from Skyworks Solutions. It shares the same core architecture and package type with variants like SI52111-B3-GM2 and SI52111-A2-GM2. Differences typically lie in internal programming configurations or specific feature sets enabled by the alphanumeric suffix codes.

Replacement Considerations

Direct replacements include SI52111-B3-GM2 and SI52111-A2-GM2. Verify pinout compatibility and electrical parameters before substitution. Note that some variants may offer additional features like spread spectrum which might require firmware or hardware adjustments.
