3 Description

The TUSB212 is a USB High-Speed (HS) signal

conditioner, designed to compensate for ISI signal

loss in a transmission channel.

TUSB212 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 TUSB212 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 helps to pass

USB High Speed electrical compliance tests.

In addition, TUSB212 is compatible with the USB On-

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