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.
