A data pulse receiver for detecting and amplifying substantially attenuated data pulses received at gigabit-per-second rates from a differential coupler with outputs having asymmetrical dc characteristics. The receiver, in a preferred embodiment, has grounded base differential amplifiers to give impedance matching, a biasing resistor connected to a separate ground termin al for biasing one of the differential amplifiers, and a matching resistor, connected at only one of its terminals, to compensate for the stray capacitance of the biasing resistor. A regenerative flip-flop with programmable tail current provides hysteresis in order to suppress unwanted noise. The receiver may also include means for automatic adjustment of the hysteresis level.
