SI5332AD09343-GM3R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332AD09343-GM3R is a factory-programmed, any-frequency clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize frequencies up to 333.33 MHz with low phase jitter of 190 fs RMS when using an external crystal. The device supports up to twelve differential or twenty-four LVCMOS outputs across three package options. It features user-configurable signal formats including LVDS, LVPECL, HCSL, and LVCMOS, with independent output supply pins for mixed-voltage applications. Operating within a temperature range of –40 to +85 °C, it integrates spread spectrum capabilities and non-volatile memory for configuration storage.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '09343' corresponds to the required frequency plan and output configuration, as this suffix denotes a factory-programmed custom part. Confirm the package type (GM3 indicates 48-pin QFN/LGA) matches the PCB land pattern requirements. Ensure the design accommodates the specified operating temperature range and RoHS-6 compliance standards.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the SI5332A variant for integer and fractional mode operation with output frequencies up to 333.33 MHz. Choose the GM3 suffix for configurations requiring up to 12 differential outputs in a 48-pin package. Use ClockBuilder Pro software to generate the unique ordering number if a custom frequency plan is needed, ensuring the selected input source (external crystal or clock) aligns with system constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'A' designation specifies support for both integer and fractional synthesis modes with high-frequency outputs. The 'D' indicates the product revision, while 'GM3' identifies the 48-pin QFN/LGA package suitable for high-output-count applications. The trailing 'R' signifies tape and reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require matching the specific NVM configuration via ClockBuilder Pro. Generic Si5332 devices can be used if in-system programming capabilities are available. Verify pin compatibility between QFN and LGA packages if substituting different suffix variants within the same family.
