    摘要： A phase differential calculator comprises: a first phase accumulator configured to generate information indicative of the phase of a local sample clock at a first resolution; a clock generator configured to generate a generated clock and information indicative of the phase of the generated clock at a second resolution that is lower than the first resolution as a function of a phase comparison and in synchronism with a remote sample clock; and a phase comparator configured to generate the phase comparison based on a phase difference between the information indicative of the phase of the local sample clock and the information indicative of the phase of the generated clock.
