Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code assigned by ClockBuilder Pro for the custom configuration associated with this part number. Confirm that the 32-pin QFN package matches the design requirements. Ensure the external crystal specifications align with the 16 to 50 MHz input range required for free-run operation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for applications requiring up to six differential or twelve LVCMOS outputs. The Si5332A grade supports integer and fractional mode synthesis. Verify that the required output frequencies fall within the 5 to 333.33 MHz range. Consider the 190 fs RMS jitter specification when designing for high-speed serial interfaces.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'A' designation indicates support for integer and fractional synthesis modes with an external crystal. The 'D' represents the product revision. The 'GM1R' suffix denotes the RoHS-6 compliant 32-pin QFN package with tape and reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes within the Si5332 family include other grades such as Si5332B, Si5332C, or Si5332D, depending on whether integer-only or fractional synthesis is required. Package variations like GM2 (40-pin) or GM3 (48-pin) offer higher output counts but require layout adjustments.
