SI5351C-B-GMR
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
Getting Started
Start development using the Skyworks Solutions ClockBuilder Pro software to generate configuration files and register maps. For hardware evaluation, the Si5351-B-EB evaluation board provides a ready-to-use platform to test performance with different crystal frequencies and output loads.
