Abstract
One or more aspects of the present invention pertain to transferring digital data between first and second domains, where a first clock of the first domain operates at a first frequency and a second clock of the second domain operates at a second frequency, where the first frequency is higher than the second frequency, and where the first and second clocks have arbitrary phase relationships relative to one another. Techniques employed facilitate efficient digital data transfer between the first and second domains while conserving valuable semiconductor real estate.
