Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'GMR' indicates the reel packaging format when ordering. Confirm the operating temperature range meets system requirements, as the component is rated for -40°C to +85°C. Ensure the design accounts for the 36-VFQFN package dimensions and thermal pad soldering requirements. Check for any recent Product Change Notifications regarding moisture sensitivity or material updates before finalizing procurement plans.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single-output jitter-cleaned clock signal is required with flexible logic level compatibility. It is suitable for applications needing frequency multiplication or division with precise jitter specifications. Verify that the input source matches one of the supported types (LVCMOS, LVDS, LVPECL, or crystal). Ensure the power supply can provide stable voltage within the 1.71 V to 3.63 V range to maintain optimal performance.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the SI5326x-C series of jitter attenuating clocks. It is part of Skyworks' DSPLL family, designed for high-performance timing applications. The device integrates a Phase-Locked Loop (PLL) to clean and multiply input clock signals. It is commonly used in conjunction with other timing components to build robust clock trees for complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements may include other parts from the SI5326 family with compatible pinouts and electrical characteristics.
