3 Description

The TUSB5461-Q1 is a VESA® USB Type-C™ Alt

Mode redriving switch supporting USB 3.2 data rates

up to 5Gbps and DisplayPort™ 2.1 up to 8.1Gbps

for downstream facing port (Host). The device is

used for configurations C, D, and E from the VESA®

DisplayPort™ Alt Mode on 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 TUSB5461-Q1 also incorporates an adaptive

receiver equalization (AEQ) feature that can

automatically find the best ISI compensation setting

between the USB device and the TUSB5461-Q1. The

AEQ finds the best setting, therefore interoperability

between a USB Host and USB Device is vastly

improved. The TUSB5461-Q1 operates on a single

3.3V supply and comes in a Automotive Grade 2

temperature range.
