Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm interface requirements and factory programming status. Ensure the component matches the required thermal and electrical specifications for the target application environment before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a single PLL architecture with one MultiSynth is sufficient for the design. Compare against Si5361A if additional MultiSynths are needed, or Si5361C if no MultiSynths are required. Verify that the 1.3 GHz maximum output frequency meets the system requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5361 family of jitter attenuators. It shares the same 72-QFN package and general interface capabilities as other variants in the series, differing primarily in the internal number of DSPLLs and MultiSynths available for clock generation.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5361A-Axxxxx-GM offers two MultiSynths. Si5361C-Axxxxx-GM has zero MultiSynths. Si5361H-Axxxxx-GM supports higher output frequencies up to 2.75 GHz.
