This module can output sine wave and square wave, two sine waves and two square waves output
The after harmonic becomes bigger and bigger when the frequency is between 20-30MHz,and the wave form becomes unclean.
*Generated DA reference pins(PIN12)extraction is convenient for the amplitude control application of input wave form. Input voltage can be generated by variable resistance,
adjusting the resistance can get different duty ratio square wave.
* AD9580 adopts 125MHz active crystal
