Overview
The TUSB212RWBT is a USB 2.0 High-Speed (HS) signal conditioner designed by Texas Instruments to compensate for Inter-Symbol Interference (ISI) signal loss in transmission channels. This device features a patent-pending design that is agnostic to USB Low Speed (LS) and Full Speed (FS) signals, ensuring these signals remain unaffected while High Speed (HS) signals are compensated. The TUSB212 is compatible with USB On-The-Go (OTG) and Battery Charging (BC) protocols, making it versatile for various applications.
