ABSTRACT:
A method for transferring data from a first clock domain to a second clock domain. A first clock signal is generated for the first clock domain from a base clock signal. A second clock signal is generated for the second clock domain from the base clock signal. A phase relationship is detected between the first clock signal and the second clock signal. Data is transferred from the first clock domain to the second clock domain using the phase relationship between the first clock signal and the second clock signal.
