AD9850 DDS Signal Generator Module

AD9850 DDS Signal Generator Module can output sine wave, square wave, two sine wave, and two square-wave output.

Frequency harmonics in the 20-30MHz, waveform will be less and less clean. 70MHz low-pass filter, waveform SN than better Generate DA benchmark the pin (PIN12) leads conveniently to adjust the application to do the amplitude of the output waveform.

When the frequency after 20-30Mhz, Harmonic is getting bigger and bigger. The waveform will become increasingly unclean. The 70-MHz low-pass filter makes the SN ratio of the waveform better. The comparator reference input voltage is generated by the variable resistor, adjust the resistance can be different duty cycle square wave.

Features:

• 2 sine wave and 2 square wave output.
• AD9850: 0-40MHz.
• After the 20-30MHz frequency harmonics increase, the waveform will be less and less clean.
• Low-pass filter with 70MHz, so the waveform better than SN.
• Parallel and serial data input we can select 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; using resistor we can adjust the duty cycle of a square wave.
