Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08965' corresponds to the required frequency plan and configuration via ClockBuilder Pro software. Confirm package type GM1 indicates a 32-pin QFN. Check current availability status as custom part numbers may have limited distribution channels.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single device must replace multiple oscillators and clock generators in mixed-voltage environments. Ensure the design requires up to six outputs with frequencies up to 333.33 MHz. Verify compatibility with I2C programming or pre-programmed factory settings if in-system reconfiguration is not needed.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 family of Any-Frequency Clock Generators. The 'A' suffix denotes support for output frequencies up to 333.33 MHz with integer and fractional synthesis. The 'GM1' suffix specifies the 32-pin QFN package supporting up to 6 outputs. The 'R' suffix typically indicates tape and reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require matching the 32-pin QFN footprint and 6-output capability. Consider Si5332A variants with different NVM codes for identical electrical specifications but different frequency plans. Cross-family substitution with Si5331 or Si534x series requires significant schematic and firmware redesign due to pinout and feature differences.
