USB3.1 Modes

The TUSB546A-DCI monitors the physical layer conditions like receiver termination, electrical idle, LFPS, and SuperSpeed signaling rate to determine the state of the USB3.1 interface. Depending on the state of the USB 3.1 interface, the TUSB546A-DCI can be in one of four primary modes of operation when USB 3.1 is enabled (CTL0 = H or CTLSEL0 = 1b1): Disconnect, U2/U3, U1, and U0.

The Disconnect mode is the state in which TUSB546A-DCI has not detected far-end termination on both upstream facing port (UFP) or downstream facing port (DFP). The disconnect mode is the lowest power mode of each of the four modes. The TUSB546A-DCI remains in this mode until far-end receiver termination has been detected on both UFP and DFP. The TUSB546A-DCI immediately exits this mode and enter U0 once far-end termination is detected.

Once in U0 mode, the TUSB546A-DCI will redrive all traffic received on UFP and DFP. U0 is the highest power mode of all USB3.1 modes. The TUSB546A-DCI remains in U0 mode until electrical idle occurs on both UFP and DFP. Upon detecting electrical idle, the TUSB546A-DCI immediately transitions to U1.

The U1 mode is the intermediate mode between U0 mode and U2/U3 mode. In U1 mode, the TUSB546A-DCI UFP and DFP receiver termination remains enabled. The UFP and DFP transmitter DC common mode is maintained. The power consumption in U1 is similar to power consumption of U0.

Next to the disconnect mode, the U2/U3 mode is next lowest power state. While in this mode, the TUSB546A-DCI periodically performs far-end receiver detection. Anytime the far-end receiver termination is not detected on either UFP or DFP, the TUSB546A-DCI leaves the U2/U3 mode and transitions to the Disconnect mode. It also monitors for a valid LFPS. Upon detection of a valid LFPS, the TUSB546A-DCI immediately transitions to the U0 mode. In U2/U3 mode, the TUSB546A-DCI receiver terminations remain enabled but the TX DC common mode voltage is not maintained.
