DDS Signal Generator Module Development Board 0-70MHz

DDS Signal Generator Module Development Board 0-70MHz Description

The module can output sine wave and square wave, 2 sine wave and 2 square wave output.
AD9851: 0-70MHz
After the frequency is 20-30MHz, the harmonic becomes larger and larger, and the waveform become more and more unclean.
Square wave: 0-1MHz
Uses a 70MHz low-pass filter to make the waveform's SN ratio better

10-bit , 32-bit frequency control word
The comparator's reference input voltage is generated by a variable resistor. Adjusting this resistor can get different duty cycle square waves.
Note: In the case of outputting a sine wave, connect to the IO port of the square wave output and directly adjust
The blue potentiometer can output a square wave.
AD9851 module uses 30MHZ active crystal
