SainSmart AD9851 DDS Signal Generator Module Circuit Diagram, 2 sine wave(0-70MHz) and 2 square wave(0-1MHz) output

The SainSmart AD9851 is a highly integrated device that uses advanced DDS technology, coupled with an internal high-speed, high performance D/A converter, and comparator, to form a digitally-programmable frequency synthesizer and clock generator function. When referenced to an accurate clock source, the AD9851 generates a stable frequency and phase-programmable digitized analog output sinewave.
