ABSTRACT:
Sampling is performed. A strobe signal is generated from a first signal. Multiple sampled signals are sampled using the strobe signal. Each of the multiple sampled signals is synchronous with its own clock reference and each of clock references are asynchronous with respect to each other. Analog-to-digital conversion is performed on each sampled value of each of the multiple sampled signals. For each of the clock references that is not synchronous with the first signal, a phase comparison is performed between the clock reference and the first signal to produce a difference value. The difference value indicates a phase difference between the clock reference and the first signal. Analog-to-digital conversion of the difference value is performed at a frequency determined by the strobe signal.
