• Industrial control and automation networks

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'GMR' indicates tape-and-reel packaging versus the standard tray configuration found in other variants like the GM version. Confirm that the pre-programmed part number matches the required frequency plan exactly, as these devices are factory-configured. Check current availability status as some listings indicate limited stock or discontinuation risks for specific sub-models.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency solution with ultra-low jitter is required for four distinct clock domains. Ensure the system design accommodates the QFN-44 thermal requirements and the specified voltage rails. Compare against the generic SI5340A if programmability is needed instead of a fixed factory-programmed profile.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5340 family of silicon clock generators, which utilize MultiSynth technology for high-performance jitter attenuation. It serves as a specialized variant within the broader Skyworks portfolio, designed specifically for applications demanding precise timing integrity without the need for external programming hardware.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The SI5340A-D-GM is a similar 4-output variant but offers programmability rather than fixed frequencies. For direct functional replacement, verify if the fixed frequencies of the B05035 match the target application requirements.
