Hello everyone,

I found that the input analog signal RAIN0/GAIN0/BAIN0 (Pin2,6,14) is changed after configure the IIC register of AD9984A

My computer output a pure red colour of a whole frame

 

the amplitude is same in all line of a frame

Following is waveform when register is  configured

the amplitude of previous a few lines are lower than following lines

 

Is it because of the Clamp setting ?

 

Thanks a lot 

Best Wishes
