SI5332DC09623-GM2R

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5332DC09623-GM2R is a 12-output programmable clock generator in a 48-pin QFN package. It utilizes MultiSynth technology to synthesize frequencies up to 333.33 MHz with 0 ppm error and 190 fs RMS jitter using an external crystal. The device supports integer and fractional synthesis modes, accepting inputs from external crystals (16–50 MHz), differential clocks (10–250 MHz), or LVCMOS clocks (10–170 MHz). Outputs are configurable as LVDS, LVPECL, HCSL, or LVCMOS across independent voltage banks.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '09623' corresponds to the required frequency plan and configuration. This part number indicates a factory-programmed unit in a 48-QFN package. Confirm that the pre-loaded settings match the target application's input/output requirements before integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for designs requiring up to 12 synchronized clock outputs with mixed voltage domains. Ensure the input source matches the supported ranges: external crystal (16-50 MHz), differential clock (10-250 MHz), or LVCMOS (10-170 MHz). Verify that the required output signal formats (LVDS, LVPECL, HCSL, LVCMOS) are compatible with the destination receivers.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of Any-Frequency Clock Generators. The 'GM2R' suffix denotes the 48-pin QFN package variant supporting up to 12 outputs, RoHS-6 compliance, and tape-and-reel packaging. The 'D' revision indicates the product version, while '09623' is the unique NVM code assigned by Silicon Labs' ClockBuilder Pro software for a specific configuration.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require matching the 48-QFN package and 12-output capability. Other Si5332 variants (e.g., Si5332A/B/C/D series) may be functionally similar but require reconfiguration via ClockBuilder Pro if the NVM code differs. Ensure the replacement supports the same input types and output voltage levels.
