ABSTRACT:
An interface between two clock domains transfers data between the two clock domains without corruption or loss of data being transferred. Each clock domain has a respective clock. The two clocks have a fixed relationship. A data signal is registered in a plurality of registers in the first clock domain, the number of which is related to the fixed relationship of the clocks. Each register outputs a specific output signal, one of which is selected by a multiplexer in the second clock domain, to be output to an output register. The output register then outputs the data in synchronism with the second clock.
