Abstract:
A method of dividing the frequency of an electronic signal, the method comprising the steps of:preloading a first predetermined value in an up/down counter, clocking the up/down counter by means of said electronic signal, detecting a state in which the up/down counter has a second predetermined value, and again preloading the first predetermined value P(1:N) in the up/down counter, characterized in that the preloading operations are performed asynchronously, wherein the up/down counter comprises N flip-flops arranged in cascade, each for being preloaded periodically, while a flip-flop of the rank i (for i=2 to N) is only preloaded on the condition that the flip-flop of the rank (iâˆ’1) has been preloaded previously.
