Abstract
A clock synchronization circuit for synchronizing a first clock signal and a second clock signal for data transfer from a first function block, which is clocked by the first clock signal, to a second function block which is clocked by the second clock signal, where the clock synchronization circuit has a sampling unit for sampling the second clock signal using the first clock signal in order to generate samples and edge detection values of the sampled second clock signal, a logic circuit for outputting the generated edge detection values as a reconstructed clock signal and generating an Edge-too-Early signal and an Edge-too-Late signal; and a signal delay circuit, which delays the reconstructed second clock signal on the bases of the Edge-too-Early signal or the Edge-too-Late signal.
