    摘要: An enhanced phase-locked loop (PLL) apparatus having an aligning unit and method are described. The PLL comprises an aligning unit, a phase difference detecting unit, a charge pump, a loop filter, and a voltage-controlled oscillator. The aligning unit receives a hold signal and a reference signal for shifting an edge of the hold signal to generate the gating signal. The phase difference detecting unit detects a phase difference between the reference signal and a feedback signal and outputting an UP signal and a DOWN signal for representing the phase difference. The edge of the hold signal is aligned to an edge of the reference signal. The charge pump generates a current signal based on the UP and DOWN signals. The loop filter is used to generate a control voltage based on the current signal. The voltage-controlled oscillator receives the control voltage and generates an output signal serving as the feedback signal. The feedback signal is supplied to the optical storage system for generating subsequent data recording signals.
