Delay locked loop with common counter and method thereof

A delay locked loop circuit for delaying an input clock to lock a delay clock. The delay locked loop includes a frequency divider for dividing a frequency of the input clock by a number N to obtain a frequency-divided clock, a plurality of delay components for delaying the input clock to generate a plurality of delay clocks with different phase according to a count value, a phase detector coupled to a final delay components for detecting a phase transition between a final delay clock and the input clock, and a counter coupled to the phase detector and the frequency divider for generating the count value according to the phase transition between the final delay clock and the input clock.
