DESCRIPTION
The HD3SS213 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. It will also switch one source to one of two sinks. For
DisplayPort applications the HD3SS213 supports switching of the Auxiliary (AUX), Display Data Channel (DDC)
and Hot Plug Detect (HPD) signals in the ZEQ package.
One 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. Another application is when one source needs to switch between one
of two sinks, example would be a side connector and a docking station connector. The switching is controlled
using the Dx_SEL and AUX_SEL pins. The HD3SS213 operates from a single supply voltage of 3.3V over the
full industrial temperature range of –40°C to 105°C.
