The TUSB2E221 enables implementation of USB 2.0 compliant port on newer processors using lower voltage processes.

The TUSB2E221 is a USB eUSB2-USB 2.0 repeater supporting both device and host modes. The TUSB2E221 supports USB low-speed (LS) and full-speed (FS) signals and high-speed (HS) signals.

The TUSB2E221 is designed to interface with eUSB2 eDSPr or eUSPr operating at 1.2V single-ended signaling.

The TUSB2E221 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 17.5Ω. Device variants are available for different levels of eUSB2 trace length compensation up to 10 inches.

The I2C interface permits additional flexibility for users to fine tune the RX and TX settings of the device. The available settings are RX equalization, RX squelch threshold, RX disconnect thresholds, TX amplitude, TX slew rate and TX pre-emphasis.

Various debug options are available through the three EQ pins that can be configured to monitor various USB bus states or interrupt as well as CTA-936 UART mode control that can provide SoC debug capabilities. EQ0 and EQ1 can be used as general purpose I2C to GPIOs bridge.
