Product description: Clock Generator - signal generator - 8kHz-160MHz I2C - Si5351A - STEMMA QT / Qwiic - Adafruit 5640
Clock signal generator from Adafruit , which was based on the SI5351A chip. It has been equipped with a 25 MHz crystal oscillator and has an internal PLL loop, thanks to which it can generate any frequency in the range from 8 kHz to 160 MHz . The module uses the I2C interface to communicate with connected devices. It also has two STEMMA QT / Qwiic connectors that allow connections without soldering the leads. The Clock Generator works with a voltage of 3.3 V and 5 V.
Product compatible with Arduino and Raspberry Pi!
The manufacturer has prepared a detailed user guide that will help you get started with the generator - check it out!
