Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix B03858 against official Skyworks documentation to confirm the exact frequency plan and pinout configuration. Ensure compatibility with required I2C/SPI programming interfaces. Confirm moisture sensitivity level handling procedures during assembly. Validate that the QFN-64 thermal pad requirements match the target PCB design guidelines.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when ten independent clock outputs are required with sub-picosecond jitter specifications. Compare against the SI5340 series if fewer outputs suffice or the SI5341B variant if lower frequency ranges optimize power consumption. Ensure the system power budget accommodates the typical operating current while maintaining voltage stability within the specified 1.71 V to 3.47 V window.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5341 MultiSynth family of low-jitter clock generators. It complements the four-output Si5340 and the specialized Si5341B variants. The family utilizes advanced phase-locked loop technology to provide deterministic latency and flexible frequency synthesis for complex digital systems requiring synchronized timing signals.
