ABSTRACT:
A delay locked loop controls a plurality of delay blocks included in a delay line and thus generate a plurality of clock signals which have a frequency obtained by multiplying a frequency of a reference clock signal, an accurate phase delay, and a constant duty cycle. The delay locked loop calculates an initial delay value and applies it to the delay blocks, thereby preventing harmonic locking and reducing locking time.
