Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix B05843 against official Skyworks documentation to confirm factory-programmed parameters. Check current availability status as certain pre-configured variants may have limited distribution or end-of-life statuses. Ensure compatibility with required I2C/SMBus programming interfaces during integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when four differential or single-ended clock signals are needed with high frequency flexibility under 1028 MHz. Compare against the SI5340A series if higher maximum output frequencies above 1 GHz are not required. Confirm that the 90 fs jitter specification meets system timing budgets for the target application environment.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5340 family of ultra-low jitter clock generators. It shares architectural similarities with the Si5341 and Si5345 series but offers a reduced pin count and fewer outputs compared to the ten-output models. The MultiSynth architecture allows for flexible configuration without external components.
