I took a quick look and noticed that the DP122 input has a DP connector. What is the application for this design? The DP122 is basically a voltage follower for the DP output and a level translator for the TMDS interface. Normal application has this device inside the laptop to interface from the GPU to either the DP port or a TMDS port.
