Overview
The TUSB211RWBR, produced by Texas Instruments, is a USB 2.0 High-Speed signal conditioner designed to compensate for Inter-Symbol Interference (ISI) signal loss in transmission channels. This device is particularly useful in applications where signal integrity is crucial, such as in high-speed USB connections. The TUSB211RWBR features a patent-pending design that is agnostic to USB Low Speed (LS) and Full Speed (FS) signals, meaning these signals are unaffected, while High Speed (HS) signals are actively compensated. This ensures that the device helps in passing USB High Speed electrical compliance tests at the connector.
