3 Description

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.
