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).
