SI5332DC08824-GM1R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332DC08824-GM1R is a low-jitter, 6-output programmable clock generator from the Si5332 family. It utilizes MultiSynth technology to generate any combination of output frequencies with excellent jitter performance (190 fs rms). The device supports integer and fractional synthesis modes, allowing for 0 ppm frequency synthesis error on up to six differential clock outputs. It features user-configurable signal formats including LVDS, LVPECL, HCSL, and LVCMOS, and offers independent supply voltages for mixed-supply applications.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '08824' corresponds to the required frequency plan and configuration parameters. Confirm that the GM1 suffix indicates the 32-pin QFN package suitable for the design. Ensure compatibility with the intended input source, whether external crystal or clock, as defined in the ClockBuilder Pro configuration file associated with this part number.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single device must replace multiple oscillators or clock generators in mixed-voltage environments. The 32-QFN package limits the output count to six, making it suitable for compact designs requiring fewer than eight outputs. Verify that the required output frequencies fall within the supported range of 5 MHz to 333.33 MHz for differential outputs.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 series of any-frequency clock generators. The 'D' designation indicates an integer-only mode variant, while 'GM1' specifies the 32-pin QFN package supporting up to six outputs. The unique five-digit sequence '08824' represents a factory-programmed configuration generated via Silicon Labs' ClockBuilder Pro software utility.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require identical NVM programming or reconfiguration via ClockBuilder Pro. Other Si5332 variants with different package sizes (GM2, GM3) or synthesis modes (A, B, C grades) may serve as functional substitutes if pinout and output count requirements are met.
