SI5332AC10124-GM2R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332AC10124-GM2R is a low-jitter, programmable clock generator from the Si5332 family. It utilizes MultiSynth technology to synthesize any frequency combination with 0 ppm error on up to eight differential outputs or sixteen LVCMOS outputs. The device supports integer and fractional synthesis modes with an output frequency range of 5 MHz to 333.33 MHz for differential signals and 5 MHz to 170 MHz for LVCMOS. It features user-configurable signal formats including LVDS, LVPECL, HCSL, and LVCMOS, with independent supply banks for mixed-voltage applications.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '10124' corresponds to the required clock configuration, as this suffix denotes factory-programmed settings. Confirm the GM2R suffix indicates the 40-pin QFN package in tape and reel format. Ensure compatibility with the target system's voltage requirements and I2C interface specifications before ordering.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for designs requiring up to eight programmable clock outputs with mixed voltage supplies. The 'A' grade supports frequencies up to 333.33 MHz and uses integer/fractional synthesis. Verify that the embedded or external crystal option matches the design constraints, noting that this part number implies a specific pre-programmed configuration generated via ClockBuilder Pro software.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'GM2' designation identifies the 40-pin QFN package variant capable of supporting up to eight outputs. The 'R' suffix specifies tape and reel packaging. The unique five-digit sequence '10124' represents the non-volatile memory code assigned by Silicon Labs for a specific custom configuration.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 40-pin QFN footprint and support similar output counts. Other Si5332 variants with different package sizes (e.g., GM1 or GM3) are not pin-compatible. Substitutes should be evaluated based on jitter performance, output voltage levels, and available programming tools.
