3 Description

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.
