Abstract

The TDP142 is a linear redriver that supports DisplayPort 1.4 up to HBR3 (8.1Gbps). At these higher data rates, signal integrity issues place limitations on system trace length. The TDP142 provides 16 levels of receive linear equalization to compensate for board loss due to inter-symbol interference (ISI). This document is intended to provide general guidelines on how to use the TDP142 in a source/sink application.
