Data receiver, in particular for memory devices

A data strobe receiver includes a first comparator, which has a first input that is coupled to a first reference voltage, and a second input that is coupled to a data strobe. The data strobe receiver also includes a delay element, coupled to the output of the first comparator, and which has an enabl...

Zusammenfassung:A data strobe receiver includes a first comparator, which has a first input that is coupled to a first reference voltage, and a second input that is coupled to a data strobe. The data strobe receiver also includes a delay element, coupled to the output of the first comparator, and which has an enable input. The data strobe receiver also includes a second comparator, which has a first input that is coupled to a second voltage reference, and a second input that is coupled to the data strobe. The data strobe receiver also includes a flip-flop, which has a preset input that is coupled to the output of the second comparator; a clock input that is coupled to the output of the delay element; and an output that is coupled to the enable input of the delay element.
