8 Detailed Description

8.1 Overview

The SNx5DP149 device is a Dual Mode[1] DisplayPort retiming level shifter that supports data rates up to 3.4-

Gbps for HDMI1.4b. The device takes in AC coupled HDMI/DVI signals and level shifts them to TMDS signals

while compensating for loss and jitter through its receiver equalizer and retiming functions. The SNx5DP149 in

default configuration should meet most system needs but also provides features that allow the system

implementer flexibility in design. Programming can be accomplished through I2C[4] or pin strapping.
