Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix GM3R against official Skyworks documentation to confirm packaging details such as reel size and tape width. Ensure compatibility with moisture sensitivity levels (MSL) requirements for your assembly process. Cross-reference the part number with the latest datasheet revision to confirm electrical parameters and pinout configurations before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a high channel count (12 outputs) is required within a single package. The INT+FRAC capability allows for generating non-standard frequencies not possible with integer-only synthesizers. Verify that the operating temperature range meets system requirements, as the 'C' suffix typically denotes commercial grade (-40°C to +85°C). Confirm power supply constraints align with the 1.71V to 3.46V input range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component is part of the Si5332 family of clock generators from Skyworks Solutions. The family includes variants with different output counts (6, 8, 12) and synthesis capabilities (INT only vs. INT+FRAC). The SI5332D variant specifically provides 12 outputs with full frequency flexibility, distinguishing it from lower-channel or integer-only models in the same series.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the Si5332 family include SI5332B-D-GM3R (8 outputs) or SI5332A-D-GM3R (6 outputs) if fewer channels are acceptable. For automotive applications, consider the SI5332x-A-AMxx series which offers AEC-Q100 qualification. Ensure any substitute matches the QFN-32 package and I2C programming interface.
