Description:

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 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.

We 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. We also put level shifting circuitry on the I2C lines so you can use this chip safely with 3V or 5V logic.

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

Tutorial

How do I power and connect the breakout board?

It runs from 3 to 5 V DC with the on board 3.3 V regulator. The I2C lines are level shifted for 3 V or 5 V logic. Outputs are available via the breadboard friendly header or the optional SMA connector.

What outputs and frequencies can I generate?

There are three independent outputs, each can be set to a different frequency. Frequencies range from under 8 kHz up to over 150 MHz using the PLLs and dividers with the 25 MHz reference.

Do I need extra components or is this a complete breakout?

The breakout ships with the 25 MHz crystal reference and on board 3.3 V regulator, along with I2C level shifting. It is designed to work with 3 to 5 V systems and connects directly to a microcontroller via I2C.

Is there a library and tutorial available to get started?

Yes, there is a tutorial and a library to help you start. The code is designed for the Arduino IDE but can be ported to other platforms with I2C support.

How are the clock outputs delivered and can they be used for RF work?

Outputs are 3 Vpp and can be accessed through the breadboard header or the optional SMA connector for RF work. Each output can be configured independently to a different frequency.
