Receiver apparatus and method of propagating a signal

摘要

An apparatus and method permits quick response to a transition at an input port and subsequent propagation of the transition to the output port while being able to process a wide variety of input signal properties. A receiver apparatus comprises at least first and second receivers, each receiver accepting an input signal and tuned for optimal response to a set of known input signal properties. Either first and second primary transition propagation elements or secondary transition propagation element propagates a first transition from one of the receivers. A universal transition propagation element propagates the first transition to an output. A pass gate receives a signal based upon the output and inhibits transmission of the signal based upon the output until the first and second intermediate signals are equivalent whereupon the pass gate is placed in low impedance state permitting the signal based upon the output to be held in a storage node as the preset signal.
