In one embodiment, a method for reducing synchronizer shadow involves: 1) receiving and deserializing a serialized data flit of known length, under control of a first clock domain; 2) before receiving all of the serialized data flit, beginning to resolve a valid signal for the deserialized data flit in a second clock domain; 3) upon receiving and deserializing all of the serialized data flit, latching the deserialized data flit under control of the first clock domain; and 4) after latching the deserialized data flit, and a predetermined number of clock edges of the second clock domain after beginning to resolve the valid signal, i) resolving the valid signal; and ii) transferring the latched data flit into the second clock domain in response to the valid signal.
