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...http://www.google.fr/patents/US5481697?utm_source=gb-gplus-shareBrevet US5481697 - An apparatus for providing a clock signal for a microprocessor at a selectable one of a plurality of frequencies and for dynamically switching between any of said plurality of frequencies
