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.
