Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm tape and reel packaging requirements. Ensure the selected part number matches the required integer-only synthesis mode and integrated reference configuration. Cross-reference the exact grade designation to validate compatibility with system timing constraints and environmental specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when an integrated reference is preferred over external crystals to save board space. Confirm that the 350 MHz maximum output frequency meets design requirements. Verify that integer-only synthesis is sufficient for the application, as fractional mode is not supported in this specific grade. Check package availability for the 64-LGA form factor.
