Abstract
In one embodiment, the present invention includes a frequency divider circuit for dividing the frequency of an input signal by an odd value. In one embodiment, a frequency divider circuit includes a counter configured to receive a clock input signal and a divisor having an odd value. The counter counts clock cycles up to the divisor to generate a count. A control circuit is configured to receive the count, the divisor, and the clock input signal and generate one or more control signals to control a state of a clock output signal. A half cycle adjust circuit is configured to receive the clock input signal and the one or more control signals from the control circuit and provide an additional one-half cycle adjustment of the clock output signal. The frequency divider circuit may be a feed forward circuit with fast startup characteristics.
