Overview
The TUSB1064 is a VESA USB Type-C Alt Mode redriving switch developed by Texas Instruments. This device supports data rates up to 10 Gbps for USB 3.1 Gen 2 and up to 8.1 Gbps for DisplayPort 1.4. It is designed for upstream facing ports (sink applications) and is compliant with the VESA DisplayPort Alt Mode on USB Type-C Standard, specifically for UFP_D pin assignments C, D, and E.
The device utilizes 5th generation USB redriver technology and provides several levels of receive equalization to compensate for inter-symbol interference (ISI) caused by cable and board trace loss. It operates on a single 3.3-V power supply and is available in both commercial and industrial temperature ranges.
