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.
