    • Disclosed are a phase synchronous device for improving jitter of an output signal and a method for generating a phase synchronous signal. The phase synchronous device includes a phase detector detecting a phase difference between first and second signals to output a phase detection signal and a locking signal; a control signal generator adjusting a slope of the phase detection signal in response to the locking signal; and a charge pumping unit outputting a control voltage in response to an output of the control signal generator. The speed of a control signal applied to the charge pumping unit is adjusted in response to the locking signal, so that a peak current is reduced, and thus jitter of an output signal is improved by being reduced or minimized.
    • 公开了一种用于改善输出信号的抖动的相位同步装置和用于产生相位同步信号的方法。 相位同步装置包括相位检测器,检测第一和第二信号之间的相位差,以输出相位检测信号和锁定信号; 控制信号发生器,响应于锁定信号调节相位检测信号的斜率; 以及电荷泵送单元,其响应于所述控制信号发生器的输出而输出控制电压。 响应于锁定信号调整施加到电荷泵送单元的控制信号的速度,从而降低峰值电流,从而通过减小或最小化来提高输出信号的抖动。
