COMMUNICATION CLOCK TRANSPORT METHOD AND DEVICE

摘要

A method and apparatus for timing an output signal based on timing of an input signal is provided. A method includes determining a first clock rate derived from the input signal during a first time interval measured by a reference clock. The method also includes signal processing logic to determine a second clock rate during a second time interval based on an error signal that is calculated as a difference between the first clock rate multiplied by the second time interval and a previous value of the second clock rate multiplied by the first time interval.
