Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '10445' matches the required frequency plan, as this suffix denotes a unique factory configuration. Confirm the GM2 suffix corresponds to the 40-pin QFN package variant. Ensure the embedded or external crystal requirement aligns with the Si5332A grade specifications found in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for designs requiring up to eight differential or sixteen LVCMOS outputs. The Si5332A grade supports integer and fractional synthesis modes. Verify that the target application operates within the –40 °C to +85 °C temperature range and requires RoHS-6 compliance. Consider the independent VDDO supply options for mixed-voltage environments.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 series of any-frequency clock generators. The 'A' designation indicates support for integer and fractional synthesis modes with external crystal inputs. The 'GM2' suffix identifies the 40-pin QFN package supporting up to eight outputs. The 'R' indicates tape and reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 40-pin QFN form factor and 8-output capability. Other Si5332 variants such as SI5332BCxxxxx-GM2R may serve as alternatives if frequency ranges and synthesis modes are compatible.
