Abstract
A method and device for generating a multi-rate clock signal using a ring voltage-controlled oscillator based phase-locked loop is provided. The device includes a delay line having a length extending beyond a predetermined length required for operation of the phase-locked loop. The device further includes a tap tuning logic circuit coupled to the delay line. The delay line receives an input signal and a tuning voltage from the phase frequency detector, charge pump and loop filter circuits and generates a plurality of tapped output signals. The plurality of tapped output signals is received by the integrated digital multi-rate clock generator configured to create a plurality of clock signals.
