The GY-SI5351 Clock Signal Generator Module is a precise and flexible clock generation device designed to produce multiple independent frequencies with exceptional stability. Utilizing the SI5351A IC and I2C control interface, it allows users to configure up to three simultaneous frequency outputs ranging from 8 kHz to 160 MHz with minimal phase error. Its low-jitter performance (100 ps pp) ensures reliable operation for timing-sensitive applications such as communications, test equipment, and audio/video synchronization. The module supports both internal (25 MHz or 27 MHz crystal) and external clock inputs (CLKIN), along with features like spread-spectrum modulation, glitchless frequency switching, and programmable output strength. Compact and breadboard-friendly, it is ideal for students, engineers, and developers working on RF, timing, and digital signal applications. Featured By RoboticsBD.
