Description

The TUSB1142 is a 10Gbps USB 3.2 linear redriver with 1:2 DeMUX or 2:1 Mux function 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 TUSB1142 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 TUSB1142 incorporates an adaptive receiver equalization (AEQ) feature. The AEQ feature automatically determines what the best ISI compensation settings are 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.
