Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08839' corresponds to the required frequency plan, as this suffix denotes a factory-programmed configuration. Confirm package type GM2 matches the 40-QFN footprint requirements. Check RoHS-6 compliance status for environmental regulations. Ensure I2C interface compatibility with the host controller for any potential in-system reprogramming needs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when integer-mode synthesis is sufficient for the application, offering lower complexity than fractional modes. The 40-QFN package supports up to eight differential outputs. Verify that the input source (external crystal or clock) aligns with the system design. Consider the specific output voltage requirements (1.5V–3.3V) for each bank to ensure proper termination and signal integrity.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'D' revision indicates integer-mode operation with an external reference input. The 'GM2' suffix specifies the 40-pin QFN package variant capable of driving up to eight outputs. This part replaces multiple discrete oscillators and buffers in complex clock trees.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other Si5332D variants with different NVM codes for distinct frequency plans. For higher output counts, consider the Si5332D-GM3 (48-QFN). For fractional synthesis capabilities, evaluate Si5332A or Si5332C series devices.
