3 Description
The TUSB214 is a USB High-Speed (HS) signal
conditioner, designed to compensate for ISI signal
loss in a transmission channel.
TUSB214 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 TUSB214 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, TUSB214 is compatible with the USB On-
The-Go (OTG) and Battery Charging (BC) protocols.
The TUSB214 provides BC1.2 Charging Downstream
Port (CDP) controller for applications in which USB
host or hub do not have this support.
