Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix against official Skyworks documentation to confirm package type and tape/reel specifications. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the ordering part number matches the required electrical characteristics and packaging format before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when six distinct clock signals are required from a single source. Verify that the target application frequency remains below the 200 MHz limit. Check compatibility with the system's power supply rails, which must support the 1.71 V to 3.63 V operating range. Ensure the PCB layout accommodates the QFN-32 package dimensions.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 family of programmable clock generators. It shares core architecture with variants like the SI5332B and SI5332C-D series but differs in specific output configurations and qualification grades. The 'C' designation typically indicates commercial temperature rating, distinguishing it from automotive-grade counterparts.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other members of the Si5332 family such as the SI5332B-C-GM1R or SI5332C-D-GM1R. Verify pin-to-pin compatibility and ensure the replacement meets the same jitter and frequency requirements.
