Onite AD9850 Module DDS signal generator, Range of empty rate can be adjusted
Features:1)The module can output sine wave and square wave,two sine waves and two square waves outputAD9850: 0-40MHzAD9851: 0-70MHzSquare wave: 0-1MHz(The after harmonic becomes bigger and bigger when the frequency is between 20-30MHz,and the wave form becomes unclean.)2)70MHz low-pass filter makes the SN ratio of the wave form much better3)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, if you adjust the resistance, you can get different duty ratio square wave.4)AD9580 adopts 125MHz active crystal.
