SI5332BC08899-GM3R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332BC08899-GM3R is a factory-programmed, low-jitter clock generator from the Si5332 family. It utilizes MultiSynth technology to generate up to twelve user-configurable output frequencies with 0 ppm synthesis error. The device supports differential outputs ranging from 5 MHz to 333.33 MHz and LVCMOS outputs up to 170 MHz. It features independent supply banks for mixed-voltage applications (1.5 V to 3.3 V) and configurable signal formats including LVDS, LVPECL, HCSL, and LVCMOS. The part number indicates a specific NVM configuration assigned by ClockBuilder Pro software.

• Test and measurement instruments

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the five-digit NVM code '08899' corresponds to the required frequency plan and configuration settings. This custom part number is factory-programmed; blank devices require in-system programming via I2C or OTP. Confirm the GM3 suffix matches the 48-pin QFN package requirement for the target design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant if the application requires up to 12 differential outputs and operates within the 5 MHz to 333.33 MHz range. The 'B' designation restricts output frequencies to a maximum of 200 MHz, distinguishing it from 'A' or 'C' variants that support up to 333.33 MHz. Ensure the design accommodates the 48-QFN package dimensions and thermal requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 series of any-frequency clock generators. The 'GM3' suffix identifies the 48-pin QFN package supporting up to 12 outputs. The 'D' indicates the product revision, while the numeric sequence represents the unique non-volatile memory configuration generated by Silicon Labs ClockBuilder Pro software.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 48-QFN package and the specific NVM configuration. Generic Si5332 blank parts (e.g., SI5332B-D-GM3R) can be used if in-system programming capabilities are available. Verify that alternative SKUs support the same 200 MHz maximum output frequency limit defined by the 'B' grade.
