Dual Mode DisplayPort Source 1:2 Demultiplexer

The Parade Technologies PS8318 DisplayPort Dual Mode Source Demultiplexer accepts one DisplayPort input and provides two DisplayPort outputs. Dual Mode DisplayPort (DP) Sources are supported enabling HDMI/DVI compatibility through the use of a down-stream, level-shifting cable adapter (dongle). The device provides optimum signal integrity by directly regenerating and driving Main Link amplitude and pre-emphasis levels requested by the Sink during the DP Link Training process. Signal loss caused by the PCB traces between the DP source and PS8318 is removed by the PS8318 automatically-adjusted input equalizer. Device operation and configuration can be controlled through device pin settings or I2C bus control.
