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.
