Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix (e.g., GM vs GMR) against official Skyworks documentation to confirm packaging type, as distributor listings may vary. Confirm the factory pre-programmed configuration matches the design requirements, as custom part numbers are assigned based on specific frequency and format settings. Check for obsolescence status or limited availability notices on manufacturer channels before finalizing procurement plans.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing systems that require multiple clock outputs with different frequencies and formats from a single source. Ensure the input frequency range (crystal, differential, or LVCMOS) aligns with the available reference clock. Verify that the required output frequencies fall within the specified limits for the chosen output type, particularly noting the distinction between high-frequency differential outputs and lower-frequency LVCMOS options.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5341/40 series of low-jitter clock generators. The Si5341 variant specifically provides four inputs and ten outputs in a compact 9x9 mm QFN package. It is designed to replace multiple discrete oscillators and clock buffers, simplifying the clock tree architecture in complex electronic designs while maintaining high signal integrity.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other parts within the Si5341 family, such as the SI5341B series, which offers similar functionality but may differ in maximum output frequency specifications. Ensure that any substitute maintains compatibility with the existing I2C/SPI programming interface and physical footprint if a pin-to-pin swap is required.
