The present invention provides a method and apparatus for synchronizing signal transfers between two clock domains, where the clock domains have a gear ratio relationship. A gear ratio means that the clocks are related by a ratio, such that each clock has a different integer number of clock cycles in a common period. Also, in addition to a gear ratio relationship, the clocks may have a synchronized edge at the end of the common period. For each clock, the cycles in the common period are “colored”, i.e., identified by a number (1st, 2nd, etc.). By using the coloring technique, the appropriate clock edge to perform a data or control signal transfer can be identified. The edges are preferably chosen to minimize the latency of the transfer.
