The re-driver offers selectable gain settings in the equalizer to U2/U3: <22 mW account for channel loss. These settings are < 8mW with No Connection controlled by the EQ terminal. To compensate for Optimal Receiver Equalization: downstream transmission line losses, the output driver supports configuration of De-Emphasis and 3/6/9 dB Output Swing (terminals DE and OS). These settings Superior Drive Performance allow optimal performance, increased signaling Automatic LFPS De-Emphasis Control To Meet distance, and flexibility in placement of the TUSB551 USB 3.0 Certification Requirements in the SuperSpeed USB path.
