1:3 Demultiplexer for Dual-Mode DisplayPort™ Source, with Built-In Level Shifter for the HDMI™/DVI Output

The Parade Technologies PS8349 DisplayPort Dual-Mode Source Demultiplexer accepts one Dual-Mode DisplayPort input and provides the following:

• Two selectable Dual-Mode DisplayPort outputs. Either of these outputs can drive a native DisplayPort receptacle (supporting Dual-Mode DisplayPort), can drive a eDP Sink, or can drive a configuration switch to support DisplayPort Alt Mode on a USB Type-C® connector.

• One selectable TMDS output. Utilizing the Dual-Mode function of the Source to provide TMDS data, the HDMI/DVI output can directly drive an HDMI receptical, at TMDS data rate up to 3Gbps, or a DVI receptical up to the 1.65Gbps spec limit.

Only one output can be active at a time.

APPLICATIONS

• PC Motherboards

• Docking Stations

• Graphics Cards
