Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'GMR' indicates reel packaging when sourcing. Confirm the factory configuration code 'B04417' matches the required frequency plan, as this variant is pre-programmed. Check current availability status as custom-configured parts may have restricted stock or longer lead times compared to standard inventory items.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when ten low-jitter outputs are required for frequencies under 350 MHz. Ensure the system design accommodates the QFN-64 package thermal requirements. Verify that the input reference frequency falls within the supported range of up to 750 MHz. Compare against other Si5341 variants if higher maximum output frequencies above 350 MHz are needed.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5341 family of MultiSynth clock generators. It shares core architectural features with other models in the series, such as the SI5341B-D-GM, but differs in its specific factory-programmed output frequencies defined by the B04417 code. The GMR suffix denotes tape-and-reel packaging suitable for automated surface-mount assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional substitutes include other SI5341B variants with identical pinouts and electrical characteristics. Verify that alternative part numbers support the same 350 MHz maximum output frequency limit and 90 fs jitter specification. Ensure the replacement device offers compatible output voltage levels and drive strengths for the existing circuit design.
