Abstract
A clock signal generator having first and second coarse delay circuits connected in series delays pulses of a reference signal having period Tto produce pulses of the clock signal. The first coarse delay circuit delays pulses of the reference signal with a delay resolution of T/N seconds over a range spanning Tseconds to produce pulses of an output signal. The second coarse delay circuit delays pulses of the output signal of the first coarse delay circuit over a range spanning Tseconds with a delay resolution of T/M seconds to provide pulses of the clock signal with a timing resolution of T/(M*N) seconds when the integers N and M are relatively prime.
