摘要： A phase-locked loop includes a processing unit, a voltage-controlled oscillator, and a control unit. The processing unit generates a control voltage to a node according to a phase difference between a reference clock and a first feedback clock. The voltage-controlled oscillator generates the first feedback clock according to a voltage of the node. The control unit deactivates the voltage-controlled oscillator and provides a start voltage to the node in a power-down mode, and activates the voltage-controlled oscillator to generate the first feedback clock according to the voltage of the node in a power-on mode. The control unit stops providing the start voltage in the power-on mode.

摘要： A method for processing noise interference in a serial AT Attachment (SATA) interface. In the method, when a receiver does not receive a SOF primitive (start of frame primitive) but does receive an EOF primitive (end of frame primitive) or WTRM primitive (wait for frame termination primitive), the receiver outputs a R_OK primitive (reception with no error primitive) and sets a error flag to report to the application layer of the receiver to eliminate the interference.

摘要： The application discloses methods applied to an electronic system capable of operating in a non power saving mode and a power saving mode. According to one of the methods, the idle time when the electronic system is idle in the non-power saving mode is measured. If the idle time equals or exceeds a mode entry time, the electronic system enters the power saving mode. The power down duration when the electronic system stays in the power saving mode is measured. The mode entry time is then modified based upon the power down duration.
