ABSTRACT:
A circuit for generating clock signals includes a reference clock signal generator and a 1/N frequency divider for generating 1/N frequency divided clock signals. An up-counter counts the 1/N frequency divided clock signals until the occurrence of a first event. A programmable counter receives both an inverted count result as an initial value from the up-counter and the reference clock signals and counts the reference clock signals up to a predetermined count. When the programmable counter reaches the predetermined count it outputs a carry signal and is reset back to the initial value. As the programmable counter again counts from the initial value to the predetermined count, it again outputs a carry signal. These plurality of carry signals can be counted to provide a count corresponding to the amount of time between the occurrence of plurality of events.
