Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code 08965 matches the required frequency plan, as this suffix denotes a factory-programmed unit rather than a blank device. Confirm that the 32-pin QFN package meets board space constraints. Check current availability status as programmable variants may have longer lead times or limited stock compared to standard components.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed, customized clock tree is needed without in-system programming overhead. Ensure the input source (external crystal or clock) aligns with the design's reference requirements. Verify that the 32-pin package provides sufficient output count, as larger packages offer up to 12 outputs if more channels are required.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'A' grade indicates support for output frequencies up to 333.33 MHz with integer and fractional modes using external references. The 'GM1' suffix specifies the 32-pin QFN package supporting up to six outputs, while 'R' indicates tape-and-reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Blank devices such as SI5332AC-D-GM1R can serve as functional replacements if in-circuit programming via I2C is supported by the host system. Other grades like SI5332BC or SI5332DC offer similar pinouts but may differ in maximum output frequency capabilities or synthesis modes.
