Overview

The SI5351C-B-GMR is a highly flexible, I2C-programmable clock generator capable of synthesizing up to eight unique frequencies with 0 ppm error. It replaces multiple crystals and oscillators with a single IC, significantly reducing board space and BOM cost in complex timing architectures.

Why Choose This Part

The device features an integrated I2C interface for real-time frequency adjustments and glitchless changes, allowing for dynamic system optimization. Its excellent PSRR eliminates the need for expensive external power supply filtering, while the ability to provide level translation on individual outputs simplifies multi-voltage designs.

Applications

Communications Equipment
Generating multiple synchronized reference clocks for Ethernet switches, routers, and gateways.
Industrial Control Systems
Providing precise timing for high-speed industrial I/O and PLC backplanes.
Server and Storage
Replacing discrete oscillators in server motherboards and RAID controllers while supporting PCIe Gen 1 clocking.
Video Processing
Synthesizing non-standard frequencies for professional video broadcast and capture hardware.
