SI5332DC08807-GM1

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332DC08807-GM1 is a factory-programmed, low-jitter clock generator from the Si5332 family. It utilizes MultiSynth technology to generate integer and fractional frequencies with 0 ppm synthesis error. The device supports up to six differential outputs or twelve LVCMOS outputs in a 32-pin QFN package. Key electrical parameters include an output frequency range of 5 MHz to 333.33 MHz for differential signals and 5 MHz to 170 MHz for LVCMOS. Phase jitter performance is specified at 190 fs RMS when using an external crystal. The unit operates within a temperature range of –40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08807' matches the required frequency plan, as this suffix denotes a unique factory-programmed configuration. Confirm the GM1 suffix corresponds to the 32-pin QFN package with up to six outputs. Ensure the design accommodates the –40 °C to +85 °C operating range and RoHS-6 compliance requirements.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part if a fixed, pre-configured clock solution is preferred over in-system programming. The 32-QFN package limits the device to six differential outputs; larger packages are required for higher output counts. Verify that the input source (external crystal or clock) aligns with the programmed configuration, as the NVM stores the default initialization state.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 series of any-frequency clock generators. The 'D' indicates the product revision, while 'GM1' specifies the 32-pin QFN package variant. Unlike blank devices, this part arrives with the custom configuration burned into non-volatile memory, eliminating the need for external I2C programming during initial deployment.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require identical NVM configurations. Generic Si5332D-GM1 units can be reprogrammed using ClockBuilder Pro software to match the target specifications, provided the hardware pinout and package dimensions remain compatible.
