Overview
The TUSB211IRWBR, produced by Texas Instruments, is a USB 2.0 High-Speed (HS) signal conditioner designed to compensate for Inter-Symbol Interference (ISI) signal loss in transmission channels. This device is particularly useful in scenarios where signal integrity is compromised due to high loss PCB traces and other capacitive loads. The TUSB211IRWBR features a patent-pending design that is agnostic to USB Low Speed (LS) and Full Speed (FS) signals, ensuring these signals remain unaffected while compensating for HS signals. This makes it an essential component for ensuring compliance with USB High Speed electrical standards.
