The reason it is called a crystal set is because they use a mineral crystal as a diode for the detector in the circuit.

Web3 Aug 2012 · The AD9850 needs to run at 5V to work properly with the 125MHz crystal. It would probably be ok to wire 4 GPIO pins directly to the module since they are just inputs, but connecting via a MCP23017 effectively turns the module into another I²C peripheral and makes sure the RPi inputs are safe.
