Abstract:
A data strobe receiver comprising:a) a first comparator, the first comparator having a first input that is coupled to a first reference voltage, the first comparator having a second input that is coupled to a data strobe, the first comparator having an output; b) a delay element, the delay element having an input that is coupled to the output of the first comparator, the delay element having an enable input, the delay element having an output; c) a second comparator, the second comparator having a first input that is coupled to a second voltage reference, the second comparator having a second input that is coupled to the data strobe, the second comparator having an output; and d) a flip-flop, the flip-flop having a preset input that is coupled to the output of the second comparator, the flip-flop having a clock input that is coupled to the output of the delay element, the flip-flop having an output that is coupled to the enable input of the delay element.
