Abstract: A data input device includes a first delay line, a second delay line, a detection circuit, and a processing circuit. The detection circuit is configured to detect whether a first output data output to a system circuit deviates from a first detection range and to generate a first deviation signal in response to that the detection circuit detects the first output data deviates from the first detection range. The processing circuit normally takes a first delayed data delayed by the first delay line as the first output data. In response to that the processing circuit receives that the first deviation signal representing the first delayed data deviates from the first detection range, the processing circuit takes a second delayed data delayed by the second delay line as the first output data after the second adjustable delay magnitude of the second delay line is adjusted.
