3 Description

The TUSB1044A is a USB Type-C® Alt Mode redriver

switch that supports data rates up to 10Gbps. This

protocol-agnostic linear redriver can support USB

Type-C® Alt Mode interfaces including DisplayPort™.

The TUSB1044A provides several levels of receive

linear equalization to compensate for inter-symbol

interference (ISI) due to cable and board trace loss.

The device operates on a single 3.3V supply and

comes in a commercial and industrial temperature

range.

All four lanes of the TUSB1044A are reversible

and designed to make the device a versatile signal

conditioner that can be used in many applications.
