A synchronization circuit includes a first synchronizer, a second synchronizer, and selection circuitry. The first synchronizer is configured to synchronize a received signal to a clock signal. The second synchronizer is disposed in parallel with the first synchronizer and configured to synchronize the received signal to the clock signal. The selection circuitry is coupled to the first synchronizer and the second synchronizer. The selection circuitry is configured to provide an output value generated by the first synchronizer at an output terminal of the synchronization circuit based on the output value generated by the first synchronizer being the same as an output value generated by the second synchronizer.
