Features:
AD9851: 0-70MHz
Harmonics increases frequency increases after the 20-30MHz, the waveform Getting worse
Square Wave: 0-1MHz
Use 70MHz Low-pass filter, make Waveform SN ratio Better
Parallel and serial data input can be selected via a jumper
DA benchmark Pin (PIN12) output, Convenient to do the output waveform Rate adjustment application.
Comparator reference input voltage is Generated by the variable resistor,
Adjustment this resistance can get different duty cycle square wave
AD9851 module Using 30MHZ Active crystal
Beaster AD9851 DDS Signal Generator Module 2 Sin Wave(0-70MHz) and 2 Square Wave(0-1MHz) with 30MHZ Crystal Oscillator
