The HD3SS212 is a high-speed passive switch capable of switching two full DisplayPort 4 lane ports from one of two sources to one target location in an application. For DisplayPort applications that HD3SS212 also supports switching of the Auxiliary (AUX) and Hot Plug Detect (HPD) signals. HPD path is a buffer which requires a 125kΩ pull-down resistor on the HPDC line.

A typical application would be a mother board that includes two GPUs that need to drive one DisplayPort sink. The GPU is selected by the Dx_SEL pin. The HD3SS212 is offered in a 48-ball bfBGA package and specified to operate from a single supply voltage of 3.3V over full industrial temperature range of –40°C to 105°C.
