Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix against official documentation to confirm packaging configuration. The 'X' suffix typically indicates reel packaging, while other variants may use cut tape. Confirm moisture sensitivity level requirements and storage conditions prior to assembly. Ensure compatibility with existing PCB footprints for the WQFN-24 package. Cross-reference ordering information with manufacturer datasheets to avoid discrepancies in quantity or handling specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a dual PLL solution is required for frequencies up to 3 GHz. Consider the low power profile for battery-operated applications. Verify that the WQFN-24 package fits the design constraints. Compare performance metrics against single-PLL alternatives if only one synthesizer is needed. Ensure the input clock capabilities match the system reference source.
