SI53311-B-GMR

Clock Buffers, Drivers Overview

The SI53311-B-GMR is a low jitter universal buffer and level translator manufactured by Skyworks Solutions Inc. It features a 2:1 input multiplexer and provides up to six differential or twelve LVCMOS outputs. The device supports a wide frequency range from 1 MHz to 1.25 GHz with any-format input selection via pins. Key electrical characteristics include an ultra-low additive jitter of 100 fs rms, independent VDD and VDDO supply voltages of 1.8/2.5/3.3 V, and output clock division options of /1, /2, or /4. It operates within an industrial temperature range of –40 to +85 °C.

Clock Buffers, Drivers Feature Summary

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'B' configuration against the official Skyworks datasheet to ensure correct pinout and electrical parameters. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Check for RoHS compliance documentation as required by regional regulations.

Clock Buffers, Drivers Selection Notes

Select this component when a universal translator with integrated 2:1 mux is required for frequencies up to 1.25 GHz. Ensure the design accommodates independent power supplies for VDD and VDDO if utilizing different voltage domains. Verify that the required output formats (LVPECL, LVDS, etc.) match the pin-selected capabilities of the SI53311 family.

Clock Buffers, Drivers Part Context

The SI53311 belongs to the Si5331x family of clock drivers and distributors. It serves as a buffer and level translator designed for high-performance applications requiring signal integrity across multiple voltage domains. The -GMR suffix indicates a tape and reel packaging format suitable for automated surface-mount assembly.
