Abstract:
1. A device for coupling with a USB signal bus, comprising: a transceiver having a receive data path and a transmit data path, the receive data path coupled with the signal bus for receiving a data signal from the signal bus, and the transmit data path coupled with the signal bus; a component associated with the receive data path for processing the data signal received from the signal bus; power control logic for controlling a power mode of the component, and a clock reference signal; the device being characterized by a power consumption characteristic; wherein the component associated with the receive data path further comprises: wherein said power control logic selectively provides a power-on signal to either said first or said second synchronizer to alter the power consumption characteristic of the device from a first amount associated with the first power consumption level to a second amount associated with the second power consumption level.
