Si5351 8khz - 160Mhz Clock Generator
Never hunt around for another crystal again, with the Si5351 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
The Si5351 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 Arduino microcontroller and IDE but is easily ported to your favorite platform with I2C support
Power Pins
The clock generator on the breakout requires 3V power. Since many customers have 5V microcontrollers like Arduino, we tossed a 3.3V regulator on the board. Its ultra-low dropout so you can power it from 3.3V-5V just fine.
Vin - this is the power pin. Since the chip uses 3 VDC, we have included a voltage regulator on board that will take 3-5VDC and safely convert it down. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V
GND - common ground for power and logic
I2C Pins
SCL - I2C clock pin, connect to your microcontrollers I2C clock line. This pin is level shifted so you can use 3-5V logic, and there"s a 10K pullup on this pin.
SDA - I2C data pin, connect to your microcontrollers I2C data line. This pin is level shifted so you can use 3-5V logic, and there"s a 10K pullup on this pin.
Clock Out Pins
0, 1, and 2 - These are the 3 independent clock generated outputs. They are square waves, from 0-3V.
The clock out pins are also brought out to SMA edge-launch connectors on the other side of the PCB. You can purchase and solder on some edge-launch SMA connectors if you want to pipe the signal into an RF cable.
