SI5332C-D-GM2

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5332C-D-GM2 is an 8-output programmable clock generator housed in a 40-pin QFN package. It utilizes MultiSynth technology to synthesize frequencies up to 333.33 MHz with 0 ppm error. The device supports external crystal inputs (16–50 MHz) or differential/LVCMOS clocks. Output formats include LVDS, LVPECL, HCSL, and LVCMOS, with independent supply banks for mixed-voltage operation. Phase jitter is typically 190 fs RMS with an external crystal. It operates from –40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code assigned by ClockBuilder Pro for the desired configuration. Confirm that the 40-pin QFN package meets PCB layout requirements. Ensure the selected input source matches the Si5332C grade specifications for external crystals or clock signals.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for designs requiring eight synchronized clock outputs. The 'C' designation indicates support for integer and fractional synthesis modes with external references. Verify voltage levels for VDDO banks to ensure compatibility with downstream receivers such as PCIe Gen 1/2/3/4/5/6 devices.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of low-jitter clock generators. The GM2 suffix identifies the 40-pin variant supporting up to eight outputs. Other variants include the 32-pin (GM1) and 48-pin (GM3) packages for different output counts.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes within the same family include SI5332A-D-GM2 or SI5332B-D-GM2, depending on whether integer-only or fractional synthesis is required. Ensure pinout and electrical characteristics match the original design constraints.
