AD9850 0-40MHz can output sine wave and square wave, 2 sine wave and 2 square wave output
After the frequency is 20-30MHz, the harmonic becomes larger and larger, and the waveform will 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 DAC, 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
Parallel and serial data input can be selected via a jumper
DA produced the benchmark pin (PIN12) leads for easy adjustment to do the magnitude of the output waveform Application
Comparator reference input voltage generated by the variable resistor, the resistor can be adjusted duty cycle square wave of different. Active AD9850 125MHz crystal oscillator modules
The blue potentiometer can output a square wave

Package Include:
1 x DDS AD9850 signal generator module

Note: In the case of outputting a sine wave, connect to the IO port of the square wave output and directly adjust
