ad9681 test pattern output

Category: Hardware
Product Number: ad9681


I am confused with the ad9681 test pattern output. I am working in test pattern mode. The data I read from 4 adcs from the same bank must be the same, right? However, I'm getting data different by 1 one clock in the same bank. I applied xapp1017. where could the problem be?

I also applied digital reset.(register 0x08 -> 3)
