Product Description

The Si5351A clock generator is an I2C controller clock generator. It uses the onboard precision clock to drive multiple PLL's and clock dividers using I2C instructions. By setting up the PLL and dividers you can create precise and arbitrary frequencies. There are three independent outputs, and each one can have a different frequency. Outputs are 3Vpp, either through a breadboard-friendly header or, for RF work, an optional edge-launch SMA connector for output #1. (If you need SMA-connector outputs for all three ports, check out the non-QT breakout here)

To get you going fast, we spun up a custom-made PCB in the STEMMA QT form factor, making it easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the Si5351 or to chain it with a wide range of other sensors and accessories using a compatible cable. Onboard 3.3V LDO and level shifters means its ready for use with 3V or 5V power and logic!

Best of all, we even have a great tutorial and library to get you started! Our code is designed for use with the Arduino-compatible microcontrollers and CircuitPython/Python using I2C support.
