The 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 20Ω. 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 three 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. The TUSB2E11 is a USB compliant eUSB2 to USB 2.0 repeater supporting both device and host modes.

The TUSB4020BI is a two-port USB 2.0 hub, which provides USB high-speed/full-speed connections on the upstream port and high-speed, full-speed, or low-speed connections on the two downstream ports. When the upstream port is connected to an electrical environment that supports high-speed and full-speed/low-speed connections, high-speed and full-speed/low-speed USB connectivity is enabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports full-speed/low-speed connections, high-speed connectivity are disabled on the downstream ports. The TUSB4020BI supports per port or ganged power switching and overcurrent protection. An individually port power controlled hub switches power on or off to each downstream port as requested by the USB host. Also when an individually port power controlled hub senses an overcurrent event, only power to the affected downstream port is switched off. A ganged hub switches on power to all the downstream ports when power is required to be on for any port. The power to the downstream ports is not switched off unless all ports are in a state that allows power to be removed. Also when a ganged hub senses an overcurrent event, power to all downstream ports is switched off. The TUSB4020BI downstream ports provide support for battery charging applications by providing battery charging connected downstream port (CDP) handshaking support. The device also supports a dedicated charging port (DCP) mode when the upstream port is not connected. The DCP mode supports USB devices which support the USB Battery Charging and the Chinese Telecommunications Industry Standard YD/T 1591-2009. In addition, an automatic mode provides transparent support for BC devices and devices supporting Divider mode charging solutions when the upstream port is unconnected. The TUSB4020BI provides terminal strap configuration for some features (including battery charging support) and customization through OTP ROM, I2C EEPROM or an I2C/SMBus target interface for PID, VID, custom port and phy configurations. Custom string support is also available when using an I2C EEPROM or the I2C/SMBus target interface. The device is available in a 48-pin HTQFP package and is offered in an industrial version for operation over the temperature range of –40°C to 85°C.
