Abstract
A variable frequency clock generator provides complementary phase clock signals for a microprocessor at a selectable one of a plurality of frequencies. The outputs may be dynamically switched between any of the frequencies so that every cycle of the phase clock signals has a duration at least as great as the cycle duration of the highest frequency.
