AD9850 Module DDS Signal Generator

Date:2019-01-24 Views:

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.
