The output differential drivers of the TUSB542 provide selectable de-emphasis and output swing to achieve USB3.1 compliance, these options are configurable by means of 3-state control pins, and its available settings are listed on the Table 6-2. The level of de-emphasis required in the system depends on the channel length after the output of the re-driver. Figure 6-2 shows transmit bits with de-emphasis.
