A noise suppression circuit includes a resistor-capacitor (RC) filter where a resistive element of the RC filter has a first terminal configured to receive an input data stream and a second terminal coupled to a circuit node Vrc and a capacitive element coupled to the circuit node, a logic gate having an input coupled to the circuit node and an output configured to provide a filtered data stream, and a switch. The switch is configured to short out the resistive element of the RC filter when the input data stream and the filtered data stream are at a same value and not short out the resistive element when the input data stream and the filtered data stream are at different values.
