The TUSB1146-Q1 is a VESA® DisplayPort™ Alt Mode over USB Type-C® redriving switch that supports USB 3.2 data rates up to 10Gbps and DisplayPort™ 2.1 up to 10Gbps for downstream facing port (host). The device is used for configurations C, D, and E from the VESA® DisplayPort™ Alt Mode over USB Type-C® standard. This protocol-agnostic linear redriver is also capable of supporting other USB Type-C® Alt Mode interfaces such as HDMI Alt Mode.

The TUSB1146-Q1 also incorporates an adaptive receiver equalization (AEQ) feature that can automatically find the best ISI compensation setting between the USB device and the TUSB1146-Q1. The AEQ finds the best setting to help improve the interoperability between a USB host and USB device. The TUSB1146-Q1 operates on a single 3.3V supply and comes in an Automotive Grade 2 temperature range.
