Method and device for dividing a frequency signal |
摘要 |
A method for dividing a frequency includes the steps of receiving a first signal having a first frequency as a clock input to a first digital counter and outputting a second signal as a clock input to a second digital counter having a higher counting capacity than the first counter. The output occurs when the first counter reaches a first number of count cycles. The method also includes generating a third signal having a high cycle and a low cycle, which are determined at least as a function of the first number of count cycles. Depending on a desired division ratio, the high and low cycles may also be a function of a second number of count cycles associated with the second counter. The third signal has a frequency lower than the first frequency. |
