Abstract

Dual edge synchronizers and methods of using dual edge synchronizers to filter out glitches are provided. Dual edge synchronizers include a first two flip-flop synchronizer, a second two flip-flop synchronizer in parallel with the first two flip-flop synchronizer, a plurality of gates that receive the outputs from the two synchronizers and implement a gate logic to generate an enable signal and a D input signal that are passed to a latch. The latch generates a dual edge synchronizer output signal, wherein a change in the state of the D input signal is passed as a change in the state of the dual edge synchronizer output signal when the enable signal is high and is not passed as the dual edge synchronizer output signal when the enable signal is low.
