6.3.4 USB3.2 Dual Channel Operation (MODE = “F”)

TheTUSB1002A in dual-channel operation waits for far-end terminations on both channels 1 and 2 before transitioning to fully active state (U0 mode). This mode of operation, defined as MODE pin = ‘F’, is the most common configurable for USB3.2 Source (DFP) and Sink (UFP) applications.

In a USB3.2 x2 application, two TUSB1002A redrivers are used: One on the configuration lane and the other on the non-configuration lane. The TUSB1002A on the non-configuration lane must be placed in basic redriver mode (MODE pin = "0"). Place the TUSB1002A on the configuration lane in USB3.2 dual channel operation (MODE pin = "F"). The expectation is the USB power delivery (PD) controller will hold both TUSB1002A in shutdown mode until a connection can be established. After a connection is established, the USB PD controller places each TUSB1002A into the appropriate mode.
