Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the five-digit NVM code '09719' corresponds to the required frequency plan and output configuration. Confirm that the 48-QFN package matches the PCB footprint. Ensure the I2C interface compatibility aligns with the host controller specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant if the application requires integer-only synthesis modes limited to 200 MHz maximum output frequency. Verify that the 48-pin QFN package provides sufficient output count for the design. Check that the operating temperature range of –40 °C to +85 °C meets environmental requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 series of any-frequency clock generators. The 'B' designation in the model number specifies support for integer mode only with a maximum output frequency of 200 MHz. The 'GM3R' suffix denotes the 48-pin QFN package and tape-and-reel packaging format.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the Si5332 family architecture and 48-pin QFN package. Verify that substitute parts support the same integer-only synthesis mode and 200 MHz output limit. Ensure pinout compatibility for VDDO banks and I2C interfaces.
