有中文资料么?我想要啊!

DDS是不是与EDA相似啊?如果是与EDA相似,那我会的

中文资料很少,我只翻译了一篇。

DDS和EDA不相似,它是数字化频率合成技术。集成到一种芯片里面。一般用来产生一种高稳定度高频率的波形,再加上有些DDS芯片里面的特殊功能不同来完成各种功能。

根据器件我在弄信号发生器,用到DDS模块。用FPGA/CPLD技术,我也看了你的翻译版了,可还是有点难,能给个简单易懂的么?我想看看DDS资料,让我好设计。

谢谢你了!

简单啊?这就要看数据手册了.简单的DDS有9850和9851,复杂的是9959\9958\9956.

我想请教一下能不能用3.3V给AD9850供电啊,因为我的单片机用的是LPC2378,它的IO电压是3.3V。

现在我程序也下载到单片机里了,但是AD9850好像没有工作,不知道是什么毛病,硬件除了电源和IO电源是否匹配外别的都没问题。
