3 Description
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.
