ABSTRACT:
A receiver circuit for an integrated circuit including an input buffer having an input coupled to receive an external input signal and an output coupled to generate a buffered input signal in response to the external input signal. The input buffer is selectively enabled by a control signal. A latch is coupled to receive the buffered input signal and to generate a latched output signal. A delay circuit is coupled to receive the latched output signal and to generate a delayed signal. A comparator is coupled to receive both the latched output signal and the delayed signal. The comparator has an output coupled to the input buffer to generate the control signal.
