3 Description
The TUSB544 is a USB Type-C Alt Mode redriver
switch supporting data rates up to 8.1 Gbps This
protocol-agnostic linear redriver is capable of
supporting USB Type-C Alt Mode interfaces including
VESA DisplayPort.
The TUSB544 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 TUSB544 are reversible making it
a versatile signal conditioner that can be used in
many applications.
