Main Functions and Characters:

- Output 2 sine wave and 2 square wave:

    AD9850  0-40MHz

    AD9851  0-70MHz

- The wave increases when the frequency more than 20-30MHz, the waveform will be unclear.

    Square Wave     0-1MHz

- Low-pass filter with 70MHz, so the waveform better than SN.

- Parallel and serial data input can be selected by a jumper.

- The pin of produced DA benchmark are lead out, convenient for adjustment and application of the output waveform.

- The comparator of benchmark input voltage generated by variable resistor, adjust the resistance can get different square wave.

-  AD9850 module adopt ACTIVE CRYSTAL with 125MHz, AD9851 module adopt ACTIVE CRYSTAL with 30MHz.

- The main difference between AD9850 and AD9851

- AD9850 clock frequency up to 125MHz, the AD9851 clock frequency up to 180MHz. Output maximum frequency AD9851 than AD9850.

-  AD9850 do not have 6 times frequency, but the AD9851 have.
