The SMPTE UHD-SDI TX and RX subsystems interacts with the GT Quad via a GT Bridge Controller for SDI. The Bridge IP is programmed in duplex mode in the VCK190 example design. This is because both RX and TX subsystems are required and use the maximum line rate of 11.88 Gb/s. The following figure shows the IP settings for the SDI GT Bridge controller:
