DDS outputs sinewave and square wave upto 40 MHz. DDS is a new method to generate analog signals controlled by 32 bit control word. DDS replaces VCO modules. 1. 2 sine wave and 2 square wave output2. AD9850: 0-40MHz3. After the 20-30MHz frequency harmonics increases, the waveform will be less and less clean4. Square Wave: 0-1MHz5. Low-pass filter with 70MHz, so the waveform better than SN6. Parallel and serial data input can be selected via a jumper7. DA produced the benchmark pin (PIN12) leads for easy adjustment to do the magnitude of the output waveform Application
