PS8368 – DisplayPort V1.4 Dual-Mode Repeater / Redriver Demultiplexer

NOT RECOMMENDED FOR NEW DESIGNS
Please refer to the PS8468

The PS8368 is a Dual-Mode DisplayPort repeater, or redriver, that restores signal integrity and includes a built-in output demultiplexer.  It fully supports DisplayPort v1.4 up to the HBR3 link rate and HDMI 2.0 up to the 6.0Gbps TMDS™ data rate through the dual-mode function. The device integrates a high-speed signal equalizer and a DisplayPort and TMDS high-speed signal driver.  It is suitable for DisplayPort, Dual-Mode DisplayPort, and DisplayPort Alt Mode applications.  It removes ISI jitter and opens the NRZ data eye by restoring swing amplitude and data edge slew rates to help deliver a compliant DisplayPort output, or HDMI output from the output of a connected level-shifter device.

The PS8368 is ideal for Source, Sink and repeater device applications including docking devices. The requirement for a redriver commonly exists in a video source to remove signal loss induced by the transmission path in order to meet DisplayPort and HDMI output jitter requirements, especially at higher DisplayPort link rates or higher TMDS clock rates. The device can also be used within a DisplayPort docking device or Sink, as a repeater near the input connector, to improve receiver performance margin. Signal integrity can be further optimized through the use of the PS8368’s programmable input equalization and output pre-emphasis controls.
