USB PHY Current Consumption

4.1.7.1

Power Down Mode

In power down mode, everything is powered down, including the USB_VBUS valid detectors in typical

condition. Table 12 shows the USB interface current consumption in power down mode.

NOTE

The currents on the VDD_HIGH_CAP and VDD_USB_CAP were

identified to be the voltage divider circuits in the USB-specific level shifters.

4.1.8

PCIe 2.0 Power Consumption

Table 13 provides PCIe PHY currents under certain Tx operating modes.
