2.2.5 TUSB216I

The TUSB216I is the USB 2.0 high-speed signal conditioner that supports communication at up to 5-m cable length. Two TUSB216I components are connected to both the redrivers to compensate both AC loss (due to capacitive load) and DC loss (due to resistive load) in the transmission channel.
