  • Phase control digital frequency divider
    Patent number: 6696870
    Abstract: A digital frequency divider includes phase control of the output signal in increments of whole or half cycles of the input frequency. Whole cycle phase control is achieved by varying (logically or physically) the tap off point of a shift register loaded with a bit pattern for appropriate division. Half cycle phase changes are achieved by a multiplexer selecting one of two signals every half cycle.
