Claim:
1. An integrated circuit (IC), comprising: an injection-locked oscillator (ILO) to generate a set of oscillating signals having different phases, wherein the ILO has a natural oscillation frequency; first circuitry to inject at least one injection signal into at least one injection location of the ILO, wherein the injection signal is generated based on a first clock edge of a reference clock signal having a reference clock frequency; second circuitry to obtain one or more samples by sampling the set of oscillating signals based on a second clock edge of the reference clock signal, wherein each sample represents a signal value of an oscillating signal in the set of oscillating signals at an instance of time that corresponds to the second clock edge; and third circuitry to determine settings for the ILO based on the one or more samples, wherein the settings correspond to the natural oscillation frequency being substantially equal to the reference clock frequency or an integral multiple of the reference clock frequency.
