Signal generator 8kHz-150MHz+, I2C, 3 outputs
- SKU: SI5351
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
