Hi all,


I have some issues regarding spectrum pollution with AD9910. For example, I generated tone signal at 150 MHz, and many spurious signals appeared. I'm not using EvalBoard, but my own board (designed with LPC microprocessor). I am missing something, but i can't quite figure out what. Is there any pin that could cause this, maybe because of not being initialized (floating state) or some bit that is  not propertly set? Any kind of advice is welcomed.


Best Regards.
