Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify current availability status as specific suffix variants may have limited distribution or end-of-life status. Confirm RoHS compliance details directly with the manufacturer documentation. Ensure the ordering suffix matches the required frequency configuration exactly, as these are factory-programmed devices.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing systems requiring multiple differential and single-ended clock signals from a single source. The 350 MHz output limit suits most standard digital interfaces. Verify that the 750 MHz maximum input frequency aligns with the reference oscillator specifications in the target application design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5341 family of Ultra-Low Jitter Synthesizers. These devices utilize MultiSynth technology to generate clean clock signals. The B-series suffix typically denotes specific factory-programmed frequency configurations distinct from generic programmable variants.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 10-output count and 90 fs jitter specification. Other Si5341 variants with different output counts or higher frequency limits may require schematic adjustments. Verify pin compatibility and software configuration tools before substitution.
