The 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.
Specification:
2 sine wave and 2 square wave output;
AD9851: 0-70MHz;
After the 20-30MHz frequency harmonics increases, the waveform will be less and less clean;
Square Wave: 0-1MHz;
Low-pass filter with 70MHz, so the waveform better than SN;
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;
AD9851 module Using 30MHZ Active crystal;
AD9851 Clock frequency up to 180MHz, AD9851 has 6 octave
What's included:
1* AD9851 DDS Signal Generator Module
