Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the exact suffix 'GMR' indicates tape-and-reel packaging versus 'GM' tray packaging when sourcing. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the specific part number matches the required output frequency configuration, as custom variants are generated via ClockBuilder Pro software.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for designs requiring a single-chip solution to replace multiple oscillators. Verify that the 350 MHz maximum output frequency meets system requirements, noting that other Si5341 variants support higher frequencies up to 1.028 GHz. Check compatibility with available development kits like the Si5341-D-EVB for initial validation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5341 family of low-jitter clock generators. It utilizes proprietary MultiSynth fractional synthesizer technology combined with a wide-band PLL. The device allows independent assignment of output formats and voltages, functioning as a comprehensive clock tree on a chip for complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other SKUs within the Si5341B series with different suffixes indicating varying output configurations or packaging types. Cross-reference with Si5341C variants if higher output frequencies above 350 MHz are required, ensuring pinout and electrical specifications remain compatible.
