SI5332BC09255-GM3

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332BC09255-GM3 is a 12-output programmable clock generator from the Si5332 family, manufactured by Skyworks Solutions Inc. It utilizes MultiSynth technology to generate any-frequency outputs up to 200 MHz with 0 ppm synthesis error and 190 fs RMS jitter. The device features user-configurable output signal formats including LVDS, LVPECL, HCSL, and LVCMOS across multiple independent voltage banks (1.8 V, 2.5 V, or 3.3 V). It supports external crystal inputs (16–50 MHz) or differential/LVCMOS clock inputs. The component is housed in a 48-pin QFN package and operates within a temperature range of –40 to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific NVM code '09255' matches the required clock configuration for the target application. As this is a custom factory-programmed part, ensure the ClockBuilder Pro configuration file is archived for future re-ordering. Confirm supply availability through authorized distributors as lead times may vary based on production schedules.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the SI5332B variant specifically when the maximum required output frequency does not exceed 200 MHz. Ensure the design accommodates the 48-QFN package dimensions and thermal requirements. Verify that the input source (external crystal or clock) aligns with the device's supported frequency ranges and that the output voltage levels match the receiving components' specifications.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The 'B' designation indicates support for output frequencies up to 200 MHz, distinguishing it from the 'A', 'C', and 'E' variants which support up to 333.33 MHz. The 'GM3' suffix denotes the 48-pin QFN package capable of supporting up to 12 outputs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same family include other Si5332B-GM3 parts with different NVM codes if the clock configuration differs. For higher frequency requirements, consider Si5332A/B/C/D-GM3 variants, though electrical parameters such as max output frequency will change.
