A delay-locked loopthat includes: an adjustable frequency source () for generating a clock signal () having an adjustable frequency; an adjustment and tap selection controller () 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 () configured to receive the clock signal for generating a plurality of phase-shifted clock signals; and a first selection circuit () 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.
