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.
