3 Description
The TUSB1044 is a USB Type-C Alt Mode redriver
switch supporting data rates up to 10 Gbps. This
protocol-agnostic linear redriver is capable of
supporting USB Type-C Alt Mode interfaces including
DisplayPort.
The TUSB1044 provides several levels of receive
linear equalization to compensate for inter-symbol
interference (ISI) due to cable and board trace loss.
Operates on a single 3.3 V supply and comes in a
commercial and industrial temperature range.
All four lanes of the TUSB1044 are reversible making
it a versatile signal conditioner that can be used in
many applications.
