ABSTRACT:
A delay-locked loop300that includes: an adjustable frequency source (320) for generating a clock signal (322) having an adjustable frequency; an adjustment and tap selection controller (310) for determining a first frequency as a function of a second frequency and for causing the frequency source to adjust the frequency of the clock signal to substantially the first frequency, the second frequency being the desired frequency of a first output signal; a delay line (330) configured to receive the clock signal for generating a plurality of phase-shifted clock signals; and a first selection circuit (370) for receiving the plurality of phase-shifted clock signals and for selecting, one at a time and under the control of the adjustment and tap selection controller, a first sequence of the phase-shifted clock signals for generating the first output signal having substantially the second frequency.
