摘要： A data recovery circuit and a method thereof, which are capable of reducing locking time and jitter, are provided. The data recovery circuit includes a frequency-locked loop, a locking detector, a delay-locked loop, and a data determination circuit. The frequency-locked loop locks the frequency of an internal clock signal fed back thereto in response to an input signal with the frequency of the input signal and generates a frequency locking signal representing that the input signal is frequency-locked with the internal clock signal. The locking detector determines whether the frequency of the internal clock signal is in a predetermined frequency range of the input signal in response to the frequency locking signal and generates a phase control signal. The delay-locked loop is controlled by the phase control signal, locks the phase of the internal clock signal with the phase of the input signal, and generates a recovery locking signal. The data determination circuit receives the recovery locking signal as a clock signal, receives the input signal in response to the clock signal, and outputs the input signal as output data.

摘要： There is provided an LED circuit including a light emitting unit including a plurality of light emitting diodes; and a switching unit switching to apply only positive voltage of an AC power supply to an anode of the light emitting unit. Through this, the LED circuit can reduce complexity of a driving circuit. Further, lifespan and efficiency of the LED circuit may be improved since an electrolytic capacitor and a bridge circuit are not used. Further, any one light emitting diode may be prevented from determining the lifespan of all of the light emitting diodes since all of the light emitting diodes are driven at all times, thereby improving the lifespan of the light emitting diode.
