Overview
The TUSB544IRNQR is a USB Type-C Alt Mode redriver switch developed by Texas Instruments. This protocol-agnostic linear redriver supports data rates up to 8.1 Gbps and is designed to support USB Type-C Alt Mode interfaces, including VESA DisplayPort 1.4. The device operates on a single 3.3 V supply and is available in both commercial and industrial temperature ranges, making it versatile for various applications. It provides several levels of receive linear equalization to compensate for inter-symbol interference (ISI) due to cable and board trace loss, ensuring reliable high-speed data transmission.
