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.
