SI5332AC09628-GM3

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332AC09628-GM3 is a 12-output programmable clock generator from the Si5332 family, manufactured by Skyworks Solutions Inc. It utilizes MultiSynth technology to generate any combination of output frequencies up to 333.33 MHz with 0 ppm frequency synthesis error. The device supports integer and fractional synthesis modes and features low phase jitter performance of 190 fs RMS when using an external crystal. It operates within a temperature range of –40 to +85 °C and accepts input frequencies from external crystals (16–50 MHz), differential clocks (10–250 MHz), or LVCMOS clocks (10–170 MHz).

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code '09628' corresponds to the required clock configuration, as this suffix indicates a factory-programmed custom part number assigned via ClockBuilder Pro software. Confirm package availability in the 48-QFN format, which supports the 12-output capability defined by the 'GM3' suffix. Ensure compatibility with the intended input source and output voltage requirements before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for designs requiring high flexibility in clock tree generation from a single device. The GM3 suffix denotes the 48-pin QFN package supporting up to 12 outputs. Verify that the application requires the Integer and Fractional mode associated with the 'A' grade. Ensure the design accommodates the necessary external crystal or clock input specifications as defined in the electrical characteristics.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 family of any-frequency clock generators. The 'A' designation indicates support for both integer and fractional synthesis modes with an external crystal or clock input. The 'GM3' suffix specifies the 48-pin QFN package variant capable of driving up to 12 differential outputs. The five-digit sequence '09628' represents the unique non-volatile memory code for a pre-programmed configuration.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 48-QFN package and 12-output capability. Other Si5332 variants with different output counts (e.g., GM1 or GM2) are not pin-compatible. Alternative devices from other manufacturers may require significant schematic and layout changes due to differences in pinout and control interfaces.
