SI5332DC09655-GM1

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332DC09655-GM1 is a factory-programmed, low-jitter clock generator from the Si5332 family. It utilizes MultiSynth technology to generate any-frequency outputs with 0 ppm synthesis error and jitter performance of 190 fs RMS (external crystal) or 175 fs RMS (embedded crystal). This specific part number indicates a D-revision device in a 32-pin QFN package (GM1), supporting up to six differential outputs. The device operates within a –40 to +85 °C temperature range and supports multiple output signal formats including LVDS, LVPECL, HCSL, and LVCMOS.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the custom NVM code '09655' matches the required clock configuration, as this parameter is unique to each ClockBuilder Pro design. Confirm the GM1 suffix corresponds to the 32-pin QFN package if pin count compatibility is critical. Ensure the D-revision aligns with the intended input type (external vs. embedded crystal) specified in the design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single device must replace multiple oscillators or clock generators. The 32-QFN package limits the device to a maximum of six differential outputs. Verify that the required output frequencies fall within the 5 MHz to 333.33 MHz range for differential outputs. Check if the application requires integer-only mode, as the 'D' revision typically denotes integer mode operation depending on the specific sub-series definition.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 family of programmable clock generators. The 'D' in the model number identifies the product revision, which dictates the frequency synthesis mode (typically Integer only for D-series variants in some contexts, though datasheet notes A/B/C/D support Ext Crystal/Clock). The 'GM1' suffix specifies the 32-pin QFN package with up to 6 outputs. The '09655' is a unique NVM code assigned by Silicon Labs software for a specific configuration.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacement requires verifying the NVM configuration data. Generic Si5332 devices are blank and require programming. If replacing a fixed-frequency oscillator, ensure the new programmable device can replicate the exact frequency and jitter requirements. Check package footprint compatibility between 32-QFN variants.
