AD9850/AD9851模块是采用ADI应用最广泛的DDS（AD9850和AD9851）制作的模块。ADI的性能就不用多说了。模块主要参考AD9850和AD9851的资料做的。
主要功能特点：
* 模块能够输出正弦波和方波，2个正弦波和2个方波输出。
AD9850： 0-40MHz
AD9851： 0-70MHz
频率在20-30MHz后谐波越来越大，波形会越来越不干净。
方波： 0-1MHz
* 采用70MHz的低通滤波器，使波形的SN比更好
* 并口和串口数据输入可以通过一个跳帽选择
* 产生DA基准的管脚（PIN12）引出，方便做输出波形的幅度调节应用。
* 比较器的基准输入端电压由可变电阻产生，调节该电阻可以得到不同的占空比方波
* AD9850模块采用125MHz的有源晶振，AD9851模块采用30MHZ的有源晶振
