ABSTRACT:
A method and apparatus of a synchronizer circuit for transferring signals between two clock domains in which a first synchronizer unit and a second synchronizer unit form a hand-shaking protocol. In particular, an input event from a source clock domain is captured in an input unit and a first signal is asserted indicating that the input signal is to be transferred to a target clock domain. This first signal is synchronized to the clock signal in the target clock domain at the first synchronizer unit, causing assertion of a second signal. The second signal is coupled to an output unit which generates an output event signal for a single clock period.
