8.1 Gbps DisplayPort 1.4 1-to-2 / 2-to-1 differential mux supports DDC/AUX switching

HD3SS214 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 HD3SS214 supports switching of the Auxiliary

(AUX), Display Data Channel (DDC) and Hot Plug

Detect (HPD) signals in the nFBGA ZXH 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

DxSEL 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

DxSEL and AUXSEL pins. The HD3SS214 operates

from a single supply voltage of 3.3 V over

extended industrial temperature range -40°C to

105°C.
