Hi 

we are using LMH1297RTVT in our design. We are using it for both SDI IN and OUT-. We are using separate ICs for this. We want to know that for SDI OUT in CD mode, should the output signals to the connector be from SDI_OUT+/- or from SDI_IO+/- ?.In one of the reference designs it was from SDI_OUT+/- , however our client recommended to connect at SDI_IO+/-. Please let us know whether we need to connect the sdi Connector signals at SDI_OUT+/-  or SDI_IO+/- ,when we are using in CD mode. I have attached the schematic for your reference.
