Texas Instruments TUSB212/TUSB212-Q1 USB 2.0 HS Signal Conditioner

Texas Instruments TUSB212/TUSB212-Q1 USB 2.0 High-Speed Signal Conditioner is developed to compensate for ISI signal loss in a transmission channel. The device has a patent-pending design and is not limited to Low Speed (LS) and Full Speed (FS) signals. While HS signals are compensated the LS and FS signal characteristics are unaffected by the TUSB212/TUSB212-Q1. Fine-tuning device performance, the programmable signal AC boost, and DC boost optimize High-Speed signals at the connector, resulting in passing USB High-Speed electrical compliance tests. Additionally, the TUSB212/TUSB212-Q1 is compatible with the USB On-The-Go (OTG) and Battery Charging (BC) protocols. The TUSB212-Q1 devices are AEC-Q100 qualified for automotive applications.
