Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify availability status as distribution channels may indicate limited stock or factory special orders. Confirm RoHS compliance details and moisture sensitivity levels prior to procurement. Ensure the specific suffix matches design requirements as ordering suffixes define functional configurations. Cross-reference datasheet specifications against current project constraints.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low jitter and multi-output flexibility are critical. Verify that the required output frequencies fall within the 350 MHz limit for the B-series variant. Check compatibility with available input reference clocks up to 750 MHz. Evaluate power consumption profiles against system thermal budgets given the 115 mA to 120 mA operating currents.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5341 family of Ultra-Low Jitter Clock Generators. It shares architectural similarities with other variants like SI5341A and SI5341B-D series but differs in maximum output frequency capabilities and specific factory programming. The B-series typically targets applications requiring frequencies below 350 MHz, distinguishing it from higher-frequency A-series counterparts.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other SI5341B variants such as SI5341B-D-GM or SI5341B-D11258-GM if pinout and electrical parameters align. Verify that substitute parts support the same output logic types and jitter specifications. Ensure the replacement maintains the QFN-64 footprint and compatible supply voltage ranges.
