SI5332G-D-GM1R

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5332G-D-GM1R is a programmable clock generator featuring up to six differential outputs in a 32-pin QFN package. Utilizing MultiSynth technology, it synthesizes frequencies from 5 MHz to 333.33 MHz with 0 ppm error and phase jitter as low as 175 fs RMS when using the embedded 50 MHz crystal. The device supports LVDS, LVPECL, HCSL, and LVCMOS formats, operates on 1.8 V to 3.3 V supplies, and functions within a –40 °C to +85 °C temperature range.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the 'GM1R' suffix indicates the 32-pin QFN package with Tape & Reel packaging. Confirm the 'D' revision matches current design requirements. Check availability status as distribution channels may report limited stock or obsolescence warnings for specific revisions.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for designs requiring up to six independent clock outputs with mixed voltage domains. Ensure the application utilizes the embedded crystal feature or verify external crystal compatibility if operating in free-run mode. Validate that the required output frequencies fall within the 5 MHz to 333.33 MHz range supported by the Si5332G grade.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'G' designation specifies support for integer and fractional synthesis modes with an output frequency range up to 333.33 MHz. It is distinct from lower-frequency variants like the Si5332F, which are limited to 200 MHz.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5332 variants such as SI5332F-D-GM1R for applications not exceeding 200 MHz. Cross-model substitution requires verifying output count, package dimensions, and electrical specifications against the original design constraints.
