3 Description
TUSB2E11 is a USB compliant eUSB2 to USB 2.0
repeater supporting both device and host modes.
The device supports USB low-speed (LS), full-speed
(FS) signals, and high-speed (HS) signals.
The device has multiple patented designs to provide
robust interoperability, optimum performance, and
power.
For systems without an I2C interface, the device offers
eight individual settings with three strap-pins for USB
2.0 channel Equivalent Series Resistance (ESR) up to
20 Ω. Device variants are available for different levels
of eUSB2 trace length compensation up to 10 inches.
The I2C interface permits additional flexibility for fine
tuning of device RX equalization and TX amplitude,
slew rate and pre-emphasis to pass electrical
compliance tests and compensate for channel loss.
Various debug options are available through the 3
GPIO pins that can be configured to monitor various
USB bus states or interrupt as well as CTA-936 UART
mode that can provide SoC debug capabilities. GPIO0
and GPIO1 can be used as general purpose I2C to
GPIOs bridge.
