SI5332ED15732-GM2R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332ED15732-GM2R is a low-jitter, embedded crystal 8-output clock generator from Skyworks Solutions. It utilizes MultiSynth technology to generate any frequency up to 333.33 MHz with 0 ppm synthesis error and 190 fs RMS jitter. The device features an embedded 50 MHz reference crystal and supports integer-only frequency synthesis. It offers user-configurable output signal formats including LVDS, LVPECL, HCSL, and LVCMOS across eight differential outputs. The component operates within a temperature range of –40 to +85 °C and is housed in a 40-pin LGA package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '15732' corresponds to the required clock configuration, as this suffix indicates a factory-programmed custom part. Confirm that the integer-only synthesis mode meets system requirements, as fractional synthesis is not supported in this grade. Ensure the 40-pin LGA package footprint matches the PCB design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when an embedded crystal is preferred over an external one to save board space. The 'E' designation restricts the device to integer mode synthesis; choose 'A', 'C', 'E', 'G', or 'L' grades if fractional synthesis is needed. Verify that the 8-output count (GM2) aligns with the target application's clock tree requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 family of any-frequency clock generators. The 'E' grade specifically denotes support for embedded crystals and integer-only synthesis. The 'GM2' suffix identifies the 40-pin package variant providing up to 8 differential outputs. The 'R' suffix indicates tape and reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

For direct functional replacement with identical specifications, consider other Skyworks Si5332E variants with different NVM codes but the same GM2 package. If fractional synthesis is required, upgrade to Si5332A, C, G, or L grades. For higher output counts, switch to the Si5332-GM3 (48-pin) variant.
