  • Method for dividing the frequency of a clock signal and frequency divider circuit for implementing the method
    Patent number: 6567494
    Abstract: To divide a clock signal, a clock pulse counter counting clock pulses of the clock signal is in each case alternately reset after passing through different count differences. In this process, a first signal and a second signal is formed, the logic state of which is in each case changed with the presence of a first or, respectively, second predetermined count of the clock pulse counter by a rising or, respectively, falling clock signal edge. A divided output clock signal is then generated by a logical operation on the first and the second signal.
