Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '10124' corresponds to the required frequency plan, as this suffix denotes factory-programmed configuration data. Confirm that the GM2 package variant matches the target PCB footprint requirements. Ensure compatibility with the intended input source, whether external crystal or differential clock, prior to ordering.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the Si5332A grade for output frequencies up to 333.33 MHz; other grades may be limited to 200 MHz. Use ClockBuilder Pro software to define the custom part number based on specific frequency, format, and voltage requirements. Consider the 40-QFN package size relative to available board space and thermal dissipation needs for the application.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'GM2' suffix indicates the 40-pin QFN package supporting up to eight outputs. The 'A' designation specifies the Si5332A variant capable of higher output frequencies compared to the Si5332B/D/F/H series. The numeric suffix represents the unique factory programming configuration.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same package include other Si5332 variants such as Si5332BCxxxxx-GM2 or Si5332DCxxxxx-GM2, provided the frequency range and synthesis mode (integer/fractional) requirements are met. Verify that the replacement part supports the necessary output signal formats and voltage levels.
