  • Patent number: 6748408
    Abstract: A non-integer fractional divider divides a reference clock signal having period P by a non-integer ratio K. The divider includes multiplexers to receive a plurality N of clock signals wherein each clock signal is equally phase shifted by a P/N delay. Incrementers coupled to the multiplexers select first and second clock signals between the N clock signals. Such that the phase shift delay between the two selected clock signals is representative of the non-integer value of K. The selected clock signals are combined to output a divided clock signal. The enabling time of each selected clock signal is respectively representative of the duration of the low level and the high level of the divided clock signal.
