Texas Instruments TUSB2E11 USB 2.0 eUSB2 Repeater

Texas Instruments TUSB2E11 USB 2.0 eUSB2 Repeater is designed to support both device and host modes. The TUSB2E11 features USB low-speed (LS), full-speed (FS) signals, and high-speed (HS) signals. The device implements multiple patented designs to provide robust interoperability, optimum performance, and power.

The TI TUSB2E11 USB 2.0 eUSB2 Repeater offers eight individual settings with three strap-pins for USB 2.0 channel Equivalent Series Resistance (ESR) up to 20Ω for systems without an I2C interface. Device variants are obtainable 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 choices are available through the 3 GPIO pins configuring to monitor multiple USB bus states or interrupt and CTA-936 UART mode that can provide SoC debug capabilities. GPIO0 and GPIO1 can be used as general purpose I2C to GPIOs bridge.
