Abstract
An apparatus for synchronizing an input signal that is asynchronous to a clock signal received by the apparatus. The apparatus comprising selection circuitry configured to select the input signal and to generate a pair of intermediate signals associated with the selected input signal. The apparatus also comprising resolution circuitry configured to provide differential signals based on the pair of intermediate signals and to resolve meta-stability associated with the differential signals. The apparatus also comprising arbiter circuitry configured to determine a dominant value associated with the differential signals and to generate an intermediate output signal based on the determination. The apparatus further comprising latching circuitry configured to generate an output signal based on the intermediate output signal.
