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 SMA connector.
