Description

The TUSB1142 is a 10 Gbps 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 (10 Gbps)

and Gen1 (5 Gbps) as well as USB 3.2 low power

states (Disconnect, U1, U2, and U3).

The 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 3.3 V supply

and is available in a 40-pin WQFN package.
