Abstract
A method of asynchronously transmitting data from a first clock domain to a second clock domain by transmitting the data from the first domain to a first register; after a first period of time, transmitting the data from the first register to a second register; after a second period of time, transmitting the data from the second register to a third register; and after a third period of time, transmitting the data from the third register to the second clock domain, where the first clock domain operates at a first frequency C1, and the second clock domain operates at a second frequency C2, C1 being faster than C2; and where: the first period of time is determined by C1; and the second and third periods of time are determined by a third frequency C3 that is greater than and a whole number multiple of C2.
