Abstract
A digital clock generator circuit which accepts a rate signal and a master clock signal and generates an output clock signal exhibiting a frequency which is programmed by the rate signal is disclosed. A constant duty cycle characteristic of the output clock signal is obtained regardless of the output clock signal's frequency. A memory element which generates the output signal is placed in one logical state when a counter portion of the present invention reaches a terminal count. The memory element is placed in an opposing logical state whenever the counter achieves 1/2 of its programmed value. A duty cycle compensator makes small timing adjustments to compensate for any truncation error which occurs in dividing the rate signal by two.
