open-in-new Find other HDMI, DisplayPort & MIPI ICs

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).
