8.5.1 DisplayPort 1:2 Mulitplexing

The TMUXHS4512 supports AC-coupled interfaces such as DisplayPort. External AC-coupling capacitors must be used on either the common side or the non-common side of the device. In this particular example, the external AC-coupling capacitors are placed on the common side. The non-common side is DC-coupled to the DP sinks. The choice of DC-coupling the non-common side or the common side is based on which DP source or DP sink meets the VIO,CM requirements of the device. If the DP source does not comply to the VIO,CM requirement, then place the AC-coupling capacitors between the DP source and TMUXHS4512. If the DP sink does not comply to the VIO,CM requirement, then place the AC-coupling capacitors between the DP sink and TMUXHS4512.
