Abstract
An integrated circuit for receiving data includes an input receiver circuit that is supplied with a data signal and a reference signal. The input receiver circuit converts the data signal into differential input control signals that are supplied to first and second signal paths. The first and second signal paths being connected in parallel. The first signal path includes a first comparator circuit that is connected, via a delay circuit and an amplifier circuit, to an output connection of the integrated circuit. The second signal path includes a second comparator circuit that is likewise connected, via a first inverter circuit and a second inverter circuit, to the output connection of the integrated circuit. The two amplifier circuits act as edge discriminators that drive each other and make it possible to generate, at the output connection, an output signal with the same duty cycle as the data signal without distortion.
