SI5332C-D-GM2R

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5332C-D-GM2R is an 8-output programmable clock generator 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, powered by independent VDDO supplies (1.5–3.3 V). Phase jitter is typically 190 fs RMS with an external crystal. It operates from –40 °C to +85 °C and complies with PCIe Gen 1/2/3/4/5/6 standards.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the 'GM2' suffix indicates the 40-pin QFN package supporting up to 8 outputs. Confirm the 'R' suffix denotes tape and reel packaging. Ensure the specific NVM code matches the required frequency plan, as custom configurations are factory-programmed.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for designs requiring eight synchronized clock signals with mixed voltage domains. The Si5332C variant supports integer and fractional synthesis modes. Use ClockBuilder Pro software to define the specific divider values and generate the unique ordering part number for factory programming.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'C' designation specifies support for both integer and fractional frequency synthesis modes. The 'D' indicates the product revision level within the datasheet specification.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Compatible replacements within the same family include Si5332A-D-GM2R and Si5332B-D-GM2R. Note that Si5332A supports higher output frequencies up to 333.33 MHz, while Si5332B is limited to 200 MHz. Package and pinout remain identical across these variants.
