Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix GM3R indicates tape and reel packaging with a standard factory quantity of 1000 units. Confirm RoHS compliance status through the official datasheet as regulatory requirements may vary by region. Check for active lifecycle status to ensure long-term availability for production designs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a single IC must generate multiple diverse clock frequencies from a single reference without external crystals. Ensure the design accommodates the 48-pin QFN thermal pad requirement for adequate heat dissipation. Verify that the required output frequencies fall within the < 333.33 MHz operational range of the internal PLL.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 series, which provides programmable clock generation solutions. The 'AD' designation typically refers to specific pinout or feature configurations within the family. It serves as a replacement for discrete clock buffer and synthesizer combinations in complex system-on-module architectures.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other Si5332 variants such as SI5332C-D-GM3R or SI5332L-D-GM3R if frequency ranges and output counts align. Cross-model compatibility depends on verifying identical pinouts and electrical specifications via official Skyworks documentation.
