8.1 Overview

The TDP142 is a DisplayPort^TM linear re-driver that supports up to 8.1 Gbps for each lane. Additionally, its transparency to the DP link training makes TDP142 a position independent device, suitable for source/sink or cable application.

The TDP142 helps the system to pass compliance of both transmitter and receiver for DisplayPort version 1.4 HBR3. The re-driver recovers incoming data by applying equalization that compensates for channel loss, and drives out signals with a high differential voltage. Each channel has a receiver equalizer with selectable gain settings. The equalization should be set based on the amount of insertion loss before the TDP142 receivers. The equalization control can be controlled by DPEQ[1:0] pins or I²C registers.

The device ultra-low-power architecture operates at a 3.3-V power supply and achieves enhanced performance. Also, it comes in a commercial temperature range and industrial temperature range.
