SI5332DC08838-GM2R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332DC08838-GM2R is a factory-programmed, low-jitter clock generator from the Si5332 family. It utilizes MultiSynth technology to generate up to eight differential or sixteen LVCMOS outputs with zero ppm frequency synthesis error. The device supports integer-only mode and operates within a 5 MHz to 200 MHz output range. It features user-configurable signal formats including LVDS, LVPECL, HCSL, and LVCMOS, with independent supply voltages for mixed-supply applications. The component is housed in a 40-pin QFN package and includes an embedded 50 MHz crystal option.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix GM2R corresponds to the tape and reel packaging format. Confirm that the custom part number indicates factory programming rather than blank in-system programmability. Ensure compatibility with the required output count and voltage levels before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for designs requiring up to eight outputs with integer-only synthesis constraints. Verify that the 200 MHz maximum output frequency meets system requirements. Check if the 40-pin QFN package fits the PCB layout constraints. Consider the embedded crystal option if external reference components are to be minimized.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 series of any-frequency clock generators. The 'D' designation indicates a product revision supporting integer-only mode with a 200 MHz output limit. The 'GM2' suffix specifies the 40-pin QFN package variant capable of driving up to eight differential outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 40-pin QFN footprint and support integer-only synthesis. Verify that alternative devices offer comparable jitter performance and support the same output signal formats (LVDS, LVPECL, etc.).
