Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix 'GM3R' corresponds to the 48-pin QFN package in tape and reel format. Confirm that the internal NVM code '09342' matches the required frequency plan generated by ClockBuilder Pro, as this defines the unique configuration for this part number.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for applications requiring high output counts (up to 12) and mixed voltage domains. Ensure the design accommodates the 48-pin package footprint. Verify input source compatibility, as the device requires either an external 16-50 MHz crystal or an external clock signal for operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of Any-Frequency Clock Generators. The 'A' designation indicates support for integer and fractional synthesis modes with output frequencies up to 333.33 MHz. The 'D' revision denotes the specific product iteration, while 'GM3' specifies the 48-pin RoHS-compliant package.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must be sought within the Si5332 family or compatible Skyworks MultiSynth devices. Verify pinout compatibility and ensure the substitute supports the same output count and frequency range requirements.
