Texas Instruments TUSB215/Q1 USB 2.0 High Speed Signal Conditioner

Texas Instruments TUSB215/Q1 USB 2.0 High-Speed Signal Conditioner is developed with a patent-pending design that is not limited to USB Low Speed (LS) and Full Speed (FS) signals. While HS signals are compensated, the TUSB215/Q1 LS and FS signal characteristics are unaffected. The device compensates for ISI signal loss in a transmission channel which helps pass USB electrical compliance tests. The TUSB215 is available for use in many applications with programmable signal AC and DC boost, which permits fine-tuning device performance to optimize High-Speed signals at the connector. Other features include the USB On-The-Go (OTG) and Battery Charging (BC) protocols compatibility and pin strap or I2C configurability.
