Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix B04920 against official Skyworks documentation to confirm pre-programmed frequency parameters. Custom part numbers in this series are factory-defined; ensure the selected variant matches the required clock tree configuration. Check current availability status as custom orders may have restricted distribution channels.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing systems requiring multiple disparate clock frequencies from a single source. Ensure the application supports the QFN-64 package footprint. Confirm that the input clock source falls within the supported range of 10 to 750 MHz for differential inputs or 25 to 54 MHz for external crystals.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5341 family of low-jitter clock generators. It integrates a wide-band PLL and proprietary MultiSynth fractional synthesizer technology. The architecture allows it to replace multiple discrete oscillators and clock buffers, functioning as a complete clock tree on a chip.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations
