Product Overview
The TUSB1044 is a Texas Instruments USB Type-C linear redriver for Signal_Chain designs that require USB 3.1 Gen 2 and DisplayPort 2.1 alternate-mode support. Its protocol-agnostic redriver operation supports a maximum data rate of 10 Gbps and provides four reversible bidirectional channels for USB Type-C orientation handling.
Signal conditioning is provided with linear equalization up to 11 dB at 4.05 GHz. Channel direction and equalization are controlled through GPIO and I2C, with device configuration available in GPIO mode or I2C mode. The VIO_SEL pin selects 3.3 V or 1.8 V configuration I/O and I2C interface voltage levels.
The device operates from a 3.3 V single supply, with recommended VCC conditions of 3.0 V minimum, 3.3 V nominal, and 3.6 V maximum. It is offered in a 40-pin RNQ WQFN package, 6 mm x 4 mm, 0.4 mm pitch, and includes a cross-point mux for SBU signal routing in USB Type-C and DisplayPort AUX applications.
