A slew rate control circuit is disclosed. The slew rate control circuit includes an input port to receive an input signal, a transmitter to transmit the input signal to an output port and an impedance control circuit coupled between the transmitter and the output port. The impedance control circuit has an adjustable impedance that is configured to be adjusted during a rise and a fall of the input signal using a trim code and an one shot pulse.
