Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code 'D15720' matches the required frequency plan via ClockBuilder Pro. Confirm the 'GM3R' suffix indicates the 48-pin QFN package with tape and reel packaging. Ensure the host system supports I2C configuration if in-system programming is utilized.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for designs requiring integer-only synthesis up to 200 MHz. The 'B' grade specifies integer mode operation only. Choose the GM3 variant for applications needing up to twelve differential outputs. Verify power supply requirements for independent VDDO banks.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'B' designation indicates integer-mode capability limited to 200 MHz output frequencies. The 'GM3' suffix denotes the 48-pin package supporting up to twelve outputs. The 'R' suffix specifies tape and reel packaging for automated assembly.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require matching the 48-pin QFN form factor and integer-mode 200 MHz limitation. Other Si5332B variants with different NVM codes may serve as functional substitutes if reprogrammed. Cross-grade options like Si5332D offer similar performance but must be verified for pin compatibility.
