Abstract
In one embodiment, a clock divider for producing a signal having a fifty percent duty cycle includes signal modifier circuitry connected to provide a variable clock signal. Responsive to first and second control signals of the signal modifier circuitry having respective first values, the signal modifier circuitry modifies a differential clock signal that includes first and second complementary clock signals to produce the variable clock signal, which contains an extended clock phase in every Icycle, I being an integer. The clock divider also contains counting circuitry connected to change the value of an output signal each time I cycles of the variable clock signal are counted.
