3 Description

The TDP142 is a DisplayPortTM(DP) linear redriver

that is able to snoop AUX and HPD signals. The

device complies with the VESA DisplayPort standard

Version 1.4, and supports a 1-4 lane Main Link

interface signaling up to HBR3 (8.1 Gbps per lane).

Additionally, this device is position independent. It

can be placed inside source, cable or sink effectively

providing a negative loss component to the overall

link budget.

The TDP142 provides several levels of receive linear

equalization to compensate for cable and board trace

loss due to inter symbol interference (ISI). Operates

on a single 3.3 V supply and comes in a commercial

temperature range (TDP142) and industrial

temperature range (TDP142I).
