Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix B04086 against official Skyworks documentation to confirm the exact pre-programmed frequency configuration. Ensure compatibility with the required output voltage levels and signal formats for the target application. Check for moisture sensitivity handling requirements during storage and assembly.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four independent clock outputs are needed with sub-100 fs jitter performance. Compare against the SI5341 series if ten outputs are required instead of four. Confirm that the input source matches the supported ranges of crystal, differential, or single-ended LVCMOS signals.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5340 family of low-jitter clock generators. It shares architectural similarities with the Si5341 but differs in output count. The 'GM' suffix indicates a lead-free, halogen-free RoHS-compliant package. The 'B04086' code represents a specific factory-programmed frequency set generated via ClockBuilderPro.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other parts from the Si5340 family with identical pinouts and specifications. Verify that alternative models support the same output formats and jitter requirements. Cross-reference with Si5341 variants only if additional outputs are acceptable.
