Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix GMR indicates tape and reel packaging configuration against official Skyworks documentation. Confirm RoHS compliance status directly with the manufacturer as regulatory details may vary by production batch. Ensure the part number matches the exact silicon revision required for your design, as functional differences can exist between variants within the same family despite identical base model numbers.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing systems requiring ten distinct clock signals derived from a single source with minimal jitter degradation. Compare against SI5341B variants if lower maximum output frequencies suffice, potentially offering different power characteristics. Validate that the QFN-64 thermal pad requirements align with your PCB layout capabilities for adequate heat dissipation during continuous operation at maximum load conditions.
