Abstract

A circuit for processing a differential serial digital data signal provided by a signal source includes a transmission line and an amplifier. A first capacitor couples a first conductor of the transmission line to a first input of the amplifier and a second capacitor couples a second conductor of the transmission line to a second input of the amplifier, and a termination resistor is connected between the first and second inputs of the amplifier. The capacitance value of the first capacitor is such that the time constant of the first capacitor and the termination resistor is about one-third of one bit time of the serial digital data signal and the capacitance value of the second capacitor is substantially greater than the capacitance value of the first capacitor.
