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 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.
