The TUSB544 is a USB Type-C Alt Mode redriver switch supporting data rates up to 8.1Gbps This protocol-agnostic linear redriver is capable of supporting USB Type-C Alt Mode interfacesincluding VESA DisplayPort.

The TUSB544 provides several levels of receive linear equalization to compensate forinter symbol interference (ISI) due to cable and board trace loss. Operates on a single 3.3 Vsupply and comes in a commercial and industrial temperature range.

All four lanes of the TUSB544 are reversible making it a versatile signal conditionerthat can be used in many applications.
