SI5332AC09203-GM2R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332AC09203-GM2R is a low-jitter, any-frequency clock generator from the Si5332 family. It features an integer-only synthesis mode with up to eight differential outputs in a 40-pin QFN package. The device supports output frequencies from 5 MHz to 333.33 MHz and accepts external crystals (16–50 MHz) or differential/LVCMOS clocks as inputs. Key electrical parameters include a phase jitter of 190 fs RMS with an external crystal and 175 fs RMS with an embedded option. It operates on a 1.8 V core supply with independent 1.5 V to 3.3 V output supplies.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '09203' matches the required frequency plan, as this suffix denotes a factory-programmed configuration. Confirm the 'GM2R' suffix indicates the 40-pin QFN package in tape-and-reel format. Check for RoHS-6 compliance status and moisture sensitivity level requirements during handling.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when integer-only synthesis is sufficient, offering potentially lower complexity than fractional variants. Ensure the input source matches the supported range (16–50 MHz crystal or 10–250 MHz differential clock). Verify that the 40-QFN package provides the necessary output count and voltage domain separation for the target design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 series of programmable clock generators. The 'A' designation indicates integer-only synthesis capability with high-frequency outputs up to 333.33 MHz. The 'C' in the middle likely refers to a specific revision or internal variant within the A-series architecture, while 'GM2R' specifies the physical packaging and reel orientation.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 40-QFN footprint and integer-only synthesis constraint. Other Si5332ACxxxxx-GM2R parts with different NVM codes may be pin-compatible if the frequency plan is reprogrammed via I2C, provided the host system supports in-system programming.
