Abstract
본 발명은 입력되는 데이타 열이 16비트일 경우 하이 또는 로우 레벨을 검출하기에 적당하도록 한 디지탈 데이타열 레벨 검출장치에 관한 것이다. 이러한 본 발명은 입력되는 클럭을 위상 반전시키는 인버터게이트와, 인버터게이트에서 출력되는 클럭으로 입력 데이타를 래치시키는 제1디플립플롭과, 제1디플립플롭의 출력신호가 로우상태이면 동작하여 입력값을 카운트하고 그 결과값을 출력하는 제1카운터와, 제1디플립플롭의 출력신호가 하이상태이면 동작하여 입력값을 카운트하고 그 결과치를 출력하는 제2카운터와, 제1카운터의 출력을 클럭으로하여 반전 출력신호를 래치시켜 그 결과치를 로우레벨 검출신호로 출력하는 제2디플립플롭과, 제2카운터의 출력을 클럭으로하여 반전출력신호를 래치시켜 그 결과치를 하이레벨 검출신호로 출력하는 제3디플립플롭으로 이루어진다.The present invention relates to a digital data string level detecting apparatus suitable for detecting a high or low level when an input data string is 16 bits. The present invention operates when the inverter gate phase-inverts the input clock, the first deflip-flop latching the input data with the clock output from the inverter gate, and the output signal of the first deflip-flop is low. Counts the first counter and outputs the result, a second counter that operates when the output signal of the first flip-flop is high, counts the input value and outputs the result, and clocks the output of the first counter. Second flip-flop that latches the inverted output signal and outputs the result as the low level detection signal, and latches the inverted output signal with the output of the second counter as a clock to output the result as the high level detection signal. It consists of a 3rd flip-flop.
