Hello, I'm using AD9434 to get a signal with duty, but there exist a lot of noise that fill the all 12 bits even no signal input.

I don't config any register and use the SDR mode to collect the signal with clock 320MHz. When I input a low voltage signal like 20mVpp sin(t), there exist no noise.But when I do not input any signal, I can collect full precision noise. This question influence my acquisition of a duty ratio signal. I have no idea about this question, hope your engineer can help me. Thanks!
