摘要:
A method and apparatus for synchronizing data transfers from a first clock domain to a second clock domain includes sampling data from circuit included in the first clock domain. The clock signal from the first clock domain may then be synchronized to a clock signal from the second clock domain. The sampled data may then be captured using the clock signal from the second clock domain responsive to a detection of an edge of the synchronized first clock signal.
