Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code (XXXXX) assigned by ClockBuilder Pro, as this determines the exact frequency plan. Confirm that the GM2 suffix corresponds to the required 40-QFN package. Check RoHS-6 compliance status if required by local regulations. Ensure the host system supports the I2C interface for any potential in-system reprogramming needs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when an integer-only synthesis mode is sufficient for the application, offering lower complexity than fractional variants. The 40-QFN package provides eight outputs, suitable for systems requiring multiple clock domains. Verify that the input source matches the supported ranges: external crystal (16–50 MHz), differential clock (10–250 MHz), or LVCMOS clock (10–170 MHz).

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 series of any-frequency clock generators. The 'D' designation indicates it is an integer-mode device with an output frequency range up to 200 MHz. The 'GM2' suffix specifies the 40-pin QFN package supporting up to eight outputs. It is designed to replace multiple discrete oscillators and clock buffers with a single programmable solution.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 40-QFN package and integer-only synthesis capability. Other Si5332D variants with different NVM codes may be compatible if the frequency plan is identical. Ensure substitute parts support the same output voltage banks (1.5V, 1.8V, 2.5V, or 3.3V) and signal formats.
