Abstract
A universal serial bus (USB) apparatus for lowering power consumption is provided. The universal serial bus apparatus includes a universal serial bus circuitry, a monitor unit, and a system duty clock generator. The monitor unit is used to monitor a start of frame (SOF) packet generated by the universal serial bus circuitry and generates a clock control signal accordingly. The system duty clock generator receives the clock control signal and a reference clock signal to generate a system duty clock signal. The enable or disable status of the system duty clock signal can be determined according to the SOF packet monitored by the monitor unit so as to make the universal serial bus apparatus enter into runtime idle mode to lower the power consumption.
