5.4Gbps DisplayPort 1.2a 2:1/1:2 Differential Switch



The HD3SS213 device 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 also switches 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 is 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 which the example is 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 3.3 V over the full industrial temperature range of –40°C to 105°C.
