An electronic device is described. The electronic device includes a first integrated circuit (IC) and a second integrated circuit (IC). The electronic device also includes a multiplexer configured tomultiplex a parallel data signal into a serial data signal, and a transmitter configured to transmit the serial data signal from the first IC to the second IC. The electronic device further includes areceiver configured to receive the serial data signal. The receiver includes a clamp circuit configured to clamp the voltage swing of an analog node within a determined range. The clamp also helps toextend the bandwidth of the receiver.
