SI5332BC08476-GM3R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332BC08476-GM3R is a factory-programmed, low-jitter clock generator from the Si5332 family. It utilizes MultiSynth technology to generate integer-only output frequencies up to 200 MHz with zero ppm synthesis error. The device supports up to twelve differential outputs or twenty-four LVCMOS outputs in a 48-QFN package. Key electrical parameters include a phase jitter of 190 fs RMS (external crystal) and an operating temperature range of –40 to +85 °C. Output signal formats are configurable as LVDS, LVPECL, HCSL, or LVCMOS.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific NVM code '08476' matches the required frequency plan, as this suffix denotes a factory-programmed configuration. Confirm the GM3R suffix corresponds to the 48-QFN package and tape-and-reel shipping format. Ensure the design accommodates the external crystal requirements specified for the Si5332B grade.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when integer-only frequency synthesis is sufficient for the application, as it offers lower complexity compared to fractional modes. The Si5332B grade limits maximum output frequency to 200 MHz; verify this meets system requirements against higher-frequency grades like Si5332A or C. The 48-QFN package provides the highest output count within the family.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5332 series of any-frequency clock generators. The 'B' designation indicates integer-mode operation with a 200 MHz output limit. The 'GM3' suffix identifies the 48-pin QFN package supporting up to 12 outputs. The 'R' indicates reel packaging. This specific unit is pre-programmed via ClockBuilder Pro software.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the Si5332B integer-mode specification and 48-QFN footprint. Other Si5332 variants (e.g., Si5332ACxxxxx-GM3R) offer fractional synthesis but may require reconfiguration. Blank devices (Si5332BCxxxxx-GM3R) can be programmed in-system if custom configurations are needed.
