Never hunt around for another crystal again, with the Si5351A clock generator breakout from Adafruit! This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from <8KHz up to 150+ MHz.

The Si5351A clock generator is an I2C controlled 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 - connect  either through a breadboard-friendly header add your own SMA connector to the board-edge for RF work.

Adafruit put this handy little chip onto it's own breakout board PCB, with a 3.3V LDO regulator so it can be powered from 3-5VDC. They also put level shifting circuitry on the I2C lines so you can use this chip safely with 3V or 5V logic.

Best of all, Adafruit even have a great tutorial and library to get you started! Adafruit's code is designed for use with the Arduino microcontroller and IDE but is easily ported to your favorite platform with I2C support

    Received my boards in good time as they were waiting on a shipment. Yet to be pressed into service but other amateurs I know have had success with these in their projects. (Posted on 6/06/2017)

    The tiny Adafruit si5351 clock generator arrived within the advised number of days, and is going into a DDS VFO prototype with Nano controller for an amateur radio receiver. Prefer to buy locally than from .hk or .cn despite a few extra $AUD. (Posted on 3/05/2016)
