Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix A05918 against official Skyworks documentation to confirm frequency configuration, as generic SI51218 listings may vary. Confirm current lifecycle status, as similar variants are marked End-of-Life. Ensure ESD handling protocols are followed due to humidity sensitivity classification.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when three distinct LVCMOS clock signals are required from a single source. Verify that the 170 MHz maximum output frequency meets system requirements. Ensure the PCB layout accommodates the TDFN-8 package dimensions and thermal dissipation needs for the 7.6 mA operating current.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the SI51218 family of programmable clock generators. It shares core architectural similarities with other variants like the SI51218-A07777-GMR but differs in specific programming configurations defined by the unique ordering suffix. The family targets applications requiring precise clock synthesis without external oscillators.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional substitutes include other SI51218 variants with matching pinouts. Verify electrical parameters such as jitter and voltage ranges before substitution. Cross-reference with Skyworks application notes for compatible pin-to-pin replacements within the same product line.
