According to the document ,I think if I set FMC126 in one-channel mode and give a sync signal to ev10aq190 ,the four adcs will sample signal synchronous . if I want make the sample data in a smooth curve ,what i need to do is just setting offset,gain,phase registers in appropriate values .But now ,the datas sampled show me that the four ads are not synchronous .It seems there are several delay periods among four ads.What's problem?
