 The WSPR part of the project requires an oscillator to function at around 14MHz. 
 
-For this it was chosen to use the si5351, for the good community support, and the ease of the i2c interface.

+Technically, it a low pass filter should be added, but given the harmonics of a square wave and the transmission power, for this indiviual use case, I would consider unnecessary.
