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.
