    • An apparatus and method of preventing a collision of vehicle in a crossroad are disclosed. The apparatus includes: an information generating unit installed at each of roads near the crossroad for generating real-time vehicle information by integrating vehicle's information including a speed and a position provided from the vehicles on each of the roads and traffic sign information; and an information collecting and providing unit for providing the traffic sign information to the information generating unit, collecting vehicles' information in real-time from the information providing means of a predetermined road near the crossroad, storing the collected information, and providing the collected information to vehicles approaching the crossroad through another roads for the vehicles to predict a collision in the crossroad.

    • A circuit for recovering a clock signal may include a frequency multiplier configured to generate a plurality of local clock signals, each having a different phase, based on a plurality of received global clock signals at a first frequency and each having a different phase. The local clock signals may be generated at a second frequency higher than the first frequency. The circuit may include a phase interpolator configured to generate a recovered clock signal at a given phase and at a third frequency, based on the generated local clock signals, and a phase shifter configured to adjust the phase of the recovered clock signal so as to synchronize the phase of the recovered clock signal with a phrase of input data that is input to the phase shifter.
    • 用于恢复时钟信号的电路可以包括频率乘法器,其被配置为基于多个接收的具有第一频率并且各自具有不同相位的全局时钟信号来产生每个具有不同相位的本地时钟信号。 本地时钟信号可以以比第一频率高的第二频率产生。 电路可以包括相位插值器,其被配置为基于产生的本地时钟信号在给定相位和第三频率处产生恢复的时钟信号;以及移相器,被配置为调整恢复的时钟信号的相位以便同步 恢复的时钟信号的相位与输入到移相器的输入数据的短语。
