AD9851 DDS Signal Generator Module

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
