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 full-speed (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.
