i want to send my i q data from my custom module and receive it on another board with the same setup. for this i am using fmcomms 4 board along with zc706 board with no os driver . till now i am able to send and receive data through my ip. for this i am connecting my i and q data output pins directly to the i and q input pins of ad9361 ip and am able to send and receive my data after making necessary changes.the problem with this setup is that how should i drive my data to the pins of ad9361, in that when i am not sending any data from my ip what should it force on that pins ( i and q) of ad9361. the problem is that when i send zeroes on those pins i am getting high level noise on adc on the other side when using in agc mode which is needed . any suggestions why this might be happening . thank you.
