The TUSB551 is a 4th-generation USB3.0 SuperSpeed (SS) re-driver that features a 1.8V power supply with low consumption, superior output drive performance, and automatic LFPS De-Emphasis control for full USB 3.0 compliance. The re-driver offers selectable gain settings in the equalizer to account for channel loss. These settings are controlled by the EQ terminal. To compensate for downstream transmission line losses, the output driver supports configuration of De-Emphasis and Output Swing (terminals DE and OS). These settings allow optimal performance, increased signaling distance, and flexibility in placement of the TUSB551 in the SuperSpeed USB path.
