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.
