3 Description

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 ZQE 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 HD3SS214 operates from a

single supply voltage of 3.3 V over extended

industrial temperature range -40°C to 105°C.
