Si5351 Clock Generator

The Si5351 Clock Generator Module is a versatile electronic component based on the Skyworks Si5351 chip. It functions as a programmable frequency synthesizer, allowing you to generate precise square wave clock signals ranging from 8KHz to 160MHz via an I2C interface. Unlike fixed-frequency crystals, the Si5351 allows you to configure multiple output frequencies dynamically, making it an excellent replacement for crystals, crystal oscillators, and PLLs. Key features include a wide operating voltage range (3.3V to 5V), low power consumption, and three independent clock outputs. This module is widely used in microcontroller clocking, FPGA projects, software-defined radio (SDR), and digital logic testing. Its compact breakout board design makes it easy to integrate into breadboards and custom PCBs. Choose this module for its flexibility, precision, and cost-effectiveness in creating custom clock sources for your electronics projects.
