SI5332AC09314-GM1R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332AC09314-GM1R is a factory-programmable, low-jitter clock generator from the Si5332 family. It features six differential outputs in a 32-pin QFN package. Utilizing MultiSynth technology, it supports any-frequency synthesis up to 333.33 MHz with integer and fractional modes. The device achieves 190 fs RMS jitter using an external crystal. Output signal formats are configurable as LVDS, LVPECL, HCSL, or LVCMOS. It operates on a 1.8 V, 2.5 V, or 3.3 V core supply and supports temperatures from –40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific five-digit NVM code (09314) matches the required clock configuration, as this suffix defines the unique factory-programmed settings. Confirm the GM1R suffix indicates the 32-pin QFN package and tape-and-reel packaging. Check current availability status as programmable variants may have limited stock.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed, factory-programmed solution is preferred over in-system programming. Ensure the input source matches the 'A' grade capability (external crystal or clock). Verify that the 32-QFN package provides sufficient I/O count for the design, noting that higher pin counts offer more outputs.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'A' designation indicates support for integer and fractional synthesis with external references. The 'GM1' suffix specifies the 32-pin QFN package supporting up to six outputs. The 'R' denotes tape-and-reel shipping.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require identical NVM codes or reprogramming via ClockBuilder Pro. Alternative Skyworks models include other Si5332 grades (B, C, D) with different frequency ranges or output counts. Silicon Labs offers equivalent devices within the same product line.
