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.
