Jump start help: replacing TX_DDS/RX_DC/IQ_Imbalance modules

We just brought up AD-FMCOMMS2 with KC705. And we are able to reproduce the KC705 bitstream. Now we'd like to try a quick-dirty way to get our TX/RX baseband modules work in the reference design. The plan is to replace the TX_DDS module by our TX baseband module and replace the RX DC_FILT/IQ_CORRECTION by our RX baseband module. Our TX baseband module output is at 80MSPS and RX baseband module input is at 40MSPS. We can add re-sampling block to change these two samplng rate if required. So the questions are what changes we need to make to make this scheme work. We can spend time to browse through the codes. But we'd like to get some help to get jump-started. Thanks.

 

Best regards,

Yan
