3 Description

The TUSB211 is a USB High-Speed (HS) signal

conditioner, designed to compensate for ISI signal

loss in a transmission channel.

The device 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

TUSB211.

HS

signals

are

compensated.

Programmable signal gain permits fine tuning device

performance to optimize High Speed signals at the

connector. This helps to pass USB High Speed

electrical compliance tests.

The footprint of TUSB211 does not break the

continuity of the DP/DM signal path. This permits risk

free system design of a complete USB channel.

In addition, TUSB211 is compatible with the USB On-

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