AD9851 DDS Module 70MHz Direct Digital Synthesizer Digital Signal Generator
Features:
- This module can make sine and square wave, and there are 2 sine wave outputs and 2 square-wave outputs.
- AD9850: 0-40MHz ; AD9851: 0-70MHz
- Harmonics increases when frequency is over the 20-30MHz, and the waveform will be less and less clean.
- Square Wave: 0-1MHz
- Use 70MHz low pass filter, which makes waveform better.
- Parallel and serial data input can be selected via a jumper.
- The pin which makes DA benchmark is leaded out, so it is convenient to adjust the magnitude and the duty cycle of the output square wave.
- Comparator reference input voltage generated by the variable resistor, and by this variable resistor, the duty cycle of square wave can be adjusted.
