Texas Instruments TUSB211 USB 2.0 High-Speed Signal Conditioner is a USB High-Speed (HS) signal conditioner, designed to compensate for ISI signal loss in a transmission channel. The device has a patent-pending design which is agnostic to USB Low Speed (LS) and Full Speed (FS) signals. LS and FS signal characteristics are unaffected by the TUSB211. HS signals are compensated. Programmable signal gain permits fine tuning device performance to optimize High Speed signals at the connector. This helps to pass USB High Speed electrical compliance tests. The footprint of TUSB211 does not break the continuity of the DP/DM signal path. This permits risk free system design of a complete USB channel. This device is also compatible with the USB On-The-Go (OTG) and Battery Charging (BC) protocols. Features Compatible with USB 2.0, OTG 2.0 and BC 1.2 Support for LS, FS, HS signaling Active Power Consumption of 55mW (Typical) with 3.3V Single Supply Selectable Signal Gain Via External Pulldown Resistor Does Not Break DP, DM Trace Scalable Solution - Daisy Chain Device for High Loss Applications Compact 1.6mm×1.6mm QFN Package -40°C to 85°C Industrial Temperature Range Applications Notebooks Desktops Docking Stations Cell Phones Active Cable, Cable Extenders Backplane Televisions Tablets TI Reference Design USB 2.0, USB 3.0 Re-driver Dongle Reference Design TUSB211RPTREVM Evaluation Module (EVM) Texas Instruments TUSB211RPTREVM Evaluation Module (EVM) is designed to provide a simple means of demonstrating the signal conditioning capability of the TUSB211. The TUSB211 is a High-Speed signal conditioner designed to compensate for ISI signal loss in a transmission channel. The evaluation module is pre-configured and simply connects the Type B connector on the EVM to the Type A receptacle found on a Host PC. This is done with a standard USB cable. A USB device would plug into the Type A receptacle of the evaluation board. Features Plug and Play design The TUSB211RPTREVM requires no external power as the EVM will be powered from VBUS sourced from the Host port Five sets of switches to facilitate configuration changes Includes headers for monitoring some device pins of The TUSB211 as well as power to the device Additional Resources
