9 Applications and Implementation

Note

Information in the following applications sections is not part of the TI component specification, and TI

does not warrant its accuracy or completeness. TI’s customers are responsible for determining

suitability of components for their purposes. Customers should validate and test their design

implementation to confirm system functionality.

9.1 Application Information

The HD3SS215 can be used in a variety of applications. This section shows the typical applications for

DisplayPort , DP++, and HDMI. The example diagrams illustrate using the HD3SS215 in a two source to one

sink application and a one source to two sinks application. All schematics are using the ZXH pin-out.

9.2 Typical Applications

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.
