Error-free data transfer between mesochronous clock domains can be accomplished by writing data to and reading data from a plurality of data storage elements in coordinated fashion. Write operations are controlled by execution of a state sequence synchronously with the source clock domain, and read operations are controlled by execution of the same state sequence synchronously with the destination clock domain. The states respectively correspond to the data storage elements, and the read and write executions of the state sequence do not simultaneously assume the same state.
