SparkFun Clock Generator Breakout 5P49V60 (Qwiic) Offers a wide range of customizable frequencies Redundant clock inputs with manual switchover Programmable output enable or power-down mode Four clock outputs can generate frequencies from 1-200MHz No soldering required The SparkFun Clock Generator Breakout 5P49V60 (Qwiic) offers a wide range of customizable frequencies in a wide range of different signal types using a single reference clock. Four (single output) clock outputs can generate frequencies from 1MHz-200MHz and eight (differential output) clock outputs can generate frequencies from 1MHz-350MHz. The frequency's many properties can be manipulated in code via I2C using the SparkFun Arduino Library. There are two Qwiic connectors populated on the board to easily configure the clock generator without the need for soldering to the I2C lines. However, soldering is required to connect to the clock outputs. Note: An oscilloscope is highly recommended to verify that the programmed clock signal is correct as its the only way to verify the output accurately.
