Abstract:
Programmable divider circuitry is disclosed that utilizes two cascaded divider cells to generate division ratios from 4 to 7 and utilizes an output signal from one of the divider cells to sample and synchronize the divider output signal. The operation of the programmable divider circuitry improves the consistency of duty cycles generated across the different division ratios. Further techniques are also applied to make more consistent the duty cycles depending upon the division ratio selected.
