9.2.1 DisplayPort and Dual Mode Adapter with Two Sources

The application schematic below shows the HD3SS215 in the 2:1 configuration for DisplayPort switching. The HD3SS215 receives inputs from DP Source A and DP Source B. The control pins of the device can be set to select Source A/B inputs and transfer them to port C through the Dx_SEL control pin. The schematic also shows the CONFIG1 and AUX_SEL settings to configure the HD3SS215 to work with DP++ Type 2 and Type1 adapters. For this specific schematic, the AC capacitors needed on the MainLink signal lines are shown on the Sink side of the HD3SS215. This is done to decrease the BOM. If desired the AC capacitors maybe placed in the signal path on the Source A/B side of HD3SS215. Additional diagrams are provided to show the configuration of the AUX channel for 2:1 and 1:2 DisplayPort only applications.
