ABSTRACT:
A method and device for reducing an amount of power consumed by a USB device (such as a host/hub/peripheral device which may include a receiver, phy, synchronizer, or other component associated with a data path) adapted to communicate using one or more USB signals each having a synchronization field. In this example, the method may include measuring a length of the synchronization field; associating a power down level for an idle mode based in part on the measuring operation; and disabling one or more portions of the receiver when the USB bus is inactive and/or when the USB device is transmitting data. In this manner, the one or more portions of the receiver are disabled (i.e., powered off or placed in a low power standby mode) during a times when the bus is idle or when transmitting, which can reduce the total amount of power consumed by the USB device.
