The TUSB215-Q1 is a USB High-Speed (HS) signal conditioner, designed to compensate for ISI signal loss in a transmission channel which helps passing USB electrical compliance tests.

TUSB215-Q1 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 TUSB215-Q1 while HS signals are compensated.

Programmable signal AC boost and DC boost permits fine tuning device performance to optimize High Speed signals at the connector, this allows use in many different applications.

In addition, TUSB215-Q1 is compatible with the USB On-The-Go (OTG) and Battery Charging (BC) protocols. TUSB215-Q1 further acts as Charging Downstream Port (CDP) controller and handles the necessary handshakes with the downstream device.
