    • A method for generating a spread spectrum clock includes the steps of providing a reference clock having a reference period; generating a plurality of output clocks respectively having different phases according to the reference clock; generating a first/second control signal according to the reference clock and a spread spectrum clock and starting a first/second duration accordingly; during the first/second duration, outputting a first/second selecting signal representing a first/second predetermined sequence according to the first/second control signal, wherein the second predetermined sequence is a substantial reversed sequence of the first predetermined sequence; and during the first/second duration, sequentially outputting some or all of the output clocks as the spread spectrum clock according to the first/second predetermined sequence.
    • 一种用于产生扩频时钟的方法包括以下步骤:提供具有参考周期的参考时钟; 根据参考时钟产生分别具有不同相位的多个输出时钟; 根据参考时钟和扩频时钟产生第一/第二控制信号并相应地开始第一/第二持续时间; 在第一/第二持续时间期间,根据第一/第二控制信号输出表示第一/第二预定序列的第一/第二选择信号,其中第二预定序列是第一预定序列的实质上相反的顺序; 并且在第一/第二持续时间期间,根据第一/第二预定序列顺序地输出部分或全部输出时钟作为扩频时钟。
