Title: FREQUENCY DIVIDER WITH SELECTABLE FREQUENCY AND DUTY CYCLE
Abstract:
A frequency divider system and method includes a split-divisor frequency divider module. The split-divisor frequency divider module receives a clock signal and generates an output signal based on a first divisor and a second divisor. The clock signal and output signal each have rectangular waveforms characterized by a respective frequency and pulse width. The frequency of the output signal is a selectable integer fraction of the frequency of the clock signal, the frequency of the output signal being selected based on a sum of the first and second divisors. The pulse width of the output signal is a selectable integer number of clock cycles, the pulse width of the output signal being selected based on at least one of the first divisor and the second divisor.
