3 Description

The TDP142-Q1 is a DisplayPort™ (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-lane to

4-lane Main Link interface signaling up to HBR3

(8.1Gbps per lane). Additionally, this device is position

independent. The TDP142-Q1 can be placed inside

source, cable or sink effectively providing a negative

loss component to the overall link budget.

The TDP142-Q1 provides several levels of receive

linear equalization to compensate for cable and board

trace loss due to inter symbol interference (ISI). The

TDP142-Q1 operates on a single 3.3V supply and

comes in an Automotive Grade 2 temperature range.
