Overview
The TUSB216RWBR, produced by Texas Instruments, is a third-generation USB 2.0 high-speed signal conditioner designed to enhance the signal integrity of USB 2.0 high-speed channels. This device is engineered to compensate for both AC and DC losses in the transmission channel, ensuring reliable data transmission over extended cable lengths. It is compatible with USB 2.0, OTG 2.0, and BC 1.2 protocols, making it versatile for various applications. The TUSB216RWBR features a patented design that includes an edge booster and a DC boost function to improve signal quality without altering packet timing or adding propagation delay.
