3 Description

The TUSB215 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 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 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 is compatible with the USB On-

The-Go (OTG) and Battery Charging (BC) protocols.

TUSB215 further acts as Charging Downstream Port

(CDP)

controller

and

handles

the

necessary

handshakes with the downstream device.
