Adafruit Si5351A Clock Generator Breakout Board - 8KHz to 160MHz

Key Features:

• Si5351A clock generator is an I2C controller clock generator
• Precision 25MHz crystal reference
• Generate just about any frequency, from <8KHz up to 150+ MHz
• Three independent outputs, each one can have a different frequency

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.

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