偶数倍分频：偶数倍分频应该是大家都比较熟悉的分频，通过计数器计数是完全可以实现的。如进行N倍偶数分频，那么可以通过由待分频的时钟触发计数器计数，当计数器从0计数到N/2-1时，输出时钟进行翻转，并给计数器一个复位信号，使得下一个时钟从零开始计数。以此循
环下去。这种方法可以实现任意的偶数分频。-Dual frequency many times: even several times frequency should be more familiar with all the sub-frequency, through the counter count is entirely achievable. Such as N times the frequency of even-numbered points, then by the clock frequency to be the trigger counters count, when the counter counts from 0 to N/2-1, the output clock to flip, and a reset signal to the counter, making a count clock to start from scratch. This cycle continues. This method can be achieved even at arbitrary frequency.
