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.
