7.3.2 De-Emphasis Control and Output Swing

The differential driver output provides selectable de-emphasis and output swing control in order to achieve USB3.1 compliance. The TUSB522P offers a unique way to adjust output de-emphasis and transmitter swing based on the OS1/2 and DE1/2 pins. The level of de-emphasis required in the system depends on the channel length after the output of the re-driver. The output swing and de-emphasis levels may differ for channel 1 and channel 2.
