Si5351A Clock Generator 8KHz-160MHz DC 3V-5V
Si5351A is a clock generator module with I2C communication.
It has 3 independent output pins as well as I2C SCL and SDA communication pins, and it also has 3 3 Vpp outputs..
This module features a precision 25MHz crystal, PLL and internal dividers to generate almost any frequency, from 8KHz to 150+ MHz. It is compatible with microcontrollers that have I2C communication ports, for example development boards from the Arduino family.

DOCUMENTATION AND RESOURCES
Tutorial – Use with Arduino IDE
Library for Arduino IDE: Adafruit_Si5351_Library
usein Si5351 with Arduino
To begin reading sensor data, you will need to download the Adafruit Si5351 library from the Arduino library manager.
Open up the Arduino library manager:
Search for the Adafruit Si5351 library and install it
Load Demo Sketch
Now you can open up File->Examples->Adafruit_Si5351->Si5351 and upload to your Arduino wired up to the sensor
Then open up the Serial console at 9600 baud to check the output. You should see the following:
Now you can use your oscilloscope to probe the #0, #1 and #2 outputs
Depending on your oscillioscope make and model, it may not be possible for you to verify the 112.5MHz output frequency
