Features:
*The module can output sine waves and square waves, 2 sine waves and 2 square waves. AD9850: 0-40MHz; AD9851: 0-70MHz; after the frequency is 20-30MHz, the harmonics become larger and larger, and the waveform becomes increasingly unclean. Square wave: 0-1MHz
*Adopt 70MHz low-pass filter to make the SN ratio of the waveform better
*The pin(PIN12) that generates the DA reference is leads out to facilitate the amplitude adjustment application of the output waveform.
*The reference input voltage of the comparator is generated by a variable resistor. Adjusting the resistor can obtain different duty cycle square waves.
*The AD9850 module uses a 125MHz active for crystal oscillator, and the AD9851 module uses a 30MHZ active for crystal oscillator.

Specification:
1. AD9850: 0-40MHz.
2. 2 sine wave and 2 square wave output.
3. After the 20-30MHz frequency harmonics increases, the waveform will be less and less clean.
4. Square Wave: 0-1MHz.
5. Low-pass filter with 70MHz, so the waveform is better than SN.
6. and serial data input can be via a for jumper.
7. DA produced the pin(PIN12) leads for easy adjustment to do the magnitude of the output waveform Application.
8. Comparator reference input voltage generated by the variable resistor, the resistor can be adjusted duty cycle square wave of different.
9. Active AD9850 125MHz for crystal oscillator modules.
10. Dimension:4.5cm x 2.6cm
