Texas Instruments TUSB1142 Adaptive Linear Redriver
Texas Instruments TUSB1142 Adaptive Linear Redriver is a 10Gbps USB 3.2 linear redriver with 1.2 DeMUX or 2:1 Nux for USB-C™ applications. The TUSB1142 is intended to reside between a Host and a USB-C receptacle or between a USB device and a USB-C receptacle. The TUSB11142 supports both USB 3.2 Gen2 (10Gbps) and Gen1 (5Gbps) as well as USB 3.2 low power states (Disconnect, U1, U2, and U3).
The Texas Instruments TUSB1142 incorporates an innovative, adaptive receiver equalization (AEQ) feature. The AEQ feature will automatically determine what it believes is the best ISI compensation settings between the TUSB1142 and USB device plugged into the USB connector resulting in improved interoperability. The TUSB1142 operates from a single 3.3V supply and is available in a 40-pin WQFN package.
