3 Description

TUSB2E22 enables implementation of USB 2.0

compliance port on newer processors using lower

voltage processes.

TUSB2E22 is a USB-compliant eUSB2-USB 2.0

repeater supporting both device and host modes.

TUSB2E22 supports USB low-speed (LS) and fullspeed

(FS) signals and high-speed (HS) signals.

TUSB2E22 is designed to interface with eUSB2

eDSPr or eUSPr operating at 1.2 V single-ended

signaling.

TUSB2E22 has 4 levels of compensation settings

through the EQ0 and EQ1 pins. These settings could

be used to optimize compensation for different eUSB2

channel loss profiles.
