  • Patent number: 11606094
    Abstract: A dual-edge aware clock divider configured to generate an output clock based on the input clock and a ratio of an integer M over an integer N is disclosed herein. The frequency of the output clock is based on a frequency of the input clock multiplied by the ratio (M/N), wherein M may be set to a range up to N. The output clock includes M pulses within a sequence time window having a length of N periods of the input clock. The output clock includes one or more rising edges that are substantially time aligned with one or more rising edges and one or more falling edges of the input clock, respectively. The dual-edge aware clock divider is configured to generate the output clock based on inverted and non-inverted portions of the input clock. A hybrid clock divider including the dual-edge and single-edge aware techniques is provided.
