SI5332AC08982-GM1R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332AC08982-GM1R is a factory-programmable, low-jitter clock generator from the Si5332 family. It utilizes MultiSynth technology to generate any-frequency outputs up to 333.33 MHz with 0 ppm synthesis error and 190 fs RMS jitter. The device features six differential or twelve LVCMOS outputs in a 32-pin QFN package. Outputs support configurable formats including LVDS, LVPECL, HCSL, and LVCMOS, with independent supply banks for mixed-voltage applications. Configuration is achieved via ClockBuilder Pro software for custom part numbering or through an I2C serial interface.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix 'GM1R' corresponds to the 32-pin QFN package and tape-and-reel packaging format. Confirm that the five-digit sequence '08982' represents the unique factory-programmed configuration assigned by Silicon Labs. Ensure compatibility with the required input source, as this variant supports external crystal or clock inputs rather than embedded references.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single device must replace multiple oscillators across mixed-supply domains. The 32-QFN package limits the device to six differential outputs. Verify that the application requires the A-grade performance range of 5 MHz to 333.33 MHz. For designs requiring embedded crystals, consider E/F/G/H grades instead.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 family of programmable clock generators. The 'A' designation indicates support for integer and fractional synthesis modes with an external crystal or clock input. The 'C' revision denotes specific silicon stepping within the product line. The 'GM1' suffix identifies the 32-pin QFN form factor capable of up to six differential outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5332 variants with identical output counts and package types but different frequency ranges or synthesis modes. Generic cross-model substitutes may require reconfiguration via ClockBuilder Pro if the target part supports in-system programming.
