AD9851 DDS Signal Generator Module circuit diagram
1. output 2 sine wave and 2 square wave
2. AD9851: 0-70MHz
3. After the 20-30MHz frequency harmonics
increases, the waveform will be unclean
4. Square Wave: 0-1MHz
5. Low-pass filter with 70MHz, so the
waveform better than SN
6. Parallel and serial data input can be
selected via a jumper
7. DA produced the benchmark pin (PIN12)
leads for easy adjustment to do the magnitude of the output waveform
8. Comparator reference input voltage generated
by the variable resistor, the resistor can be adjusted duty cycle square wave
9. AD9851 module use 30MHz crystal oscillator
10.The difference between AD9850 and
a.AD9850 maximum clock frequency 125MHz,
AD9851 maximum clock frequency of 180MHz. The maximum frequency output AD9851 is higher than AD9850.
b.11AD9851 has 6 octave, but AD9850 has not.
