Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '15663' matches the required frequency plan, as this suffix denotes a factory-programmed configuration. Confirm that the integer-only synthesis mode meets system requirements, as fractional synthesis is not available in this variant. Ensure the 32-pin QFN footprint aligns with the PCB layout specifications provided in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed, pre-configured clock solution is preferred over user-programmable devices. The integer-only mode simplifies design but limits frequency flexibility compared to fractional variants. Verify that the maximum output frequency of 200 MHz satisfies all downstream component requirements. Check if the 32-pin package provides sufficient I/O count for the application.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332-AM family, which offers flexible clock generation for automotive electronics. The 'D' indicates the product revision, while 'AM1' specifies the automotive grade and 32-pin package type. The unique five-digit sequence '15663' represents the custom NVM programming data assigned by ClockBuilder Pro software.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 32-pin QFN package and 6-output configuration. Other Si5332-AM variants like SI5332C-D-AM1R may serve as alternatives if fractional synthesis or higher frequency support (up to 333 MHz) is acceptable. Verify pinout compatibility and electrical specifications before substitution.
