Abstract
디지탈 테스트용 주파수 발생장치를 개시한다.Disclosed is a frequency generator for digital test.
소정의 주파수를 갖는 입력신호를 다른 소정의 주파수와 소정 크기의 위상을 지연하고 듀티비를 재조정된 신호를 발생하기 위한 주파수 발생장치에 있어서, 상기 입력신호의 주파수를 소정의 분주값으로 나누어 주파수를 출력하는 주기변이 배분기, 및 상기 주기변이 배분기로부터 출력된 신호의 주파수에 소정의 체배값을 곱하여 주파수를 출력하는 주파수 체배기를 갖는 주기 제어부 ; 상기 주기 제어부로부터 출력된 신호의 위상을 소정 크기만큼 지연하여 출력하는 지연 제어부 ; 상기 주기 제어부로부터 출력된 신호의 듀티비를 재조정하여 출력한 폭 제어부 ; 및 상기 지연 제어부로부터 출력된 신호와 상기 폭 제어부로부터 출력된 신호를 입력신호로 플립플롭하여 출력하는 플립플롭을 포함한다.There is provided a frequency generator for delaying an input signal having a predetermined frequency to a predetermined frequency and a phase of a predetermined magnitude and generating a signal whose duty ratio is readjusted. The frequency generator divides the frequency of the input signal by a predetermined frequency division value, And a frequency multiplier for multiplying a frequency of a signal output from the period variation distributor by a predetermined sieve value to output a frequency; A delay controller for delaying the phase of the signal output from the periodic controller by a predetermined magnitude; A width controller for re-adjusting the duty ratio of the signal output from the periodic control unit and outputting the adjusted duty ratio; And a flip-flop for flip-flopping the signal output from the delay control unit and the signal output from the width control unit as an input signal.
따라서, 사용하는 목적에 따라 세세한 주파수를 설정하여 제작할 수 있으며 또한 그에 따른회로가 간단하며 어떠한회로에도 쉽게 적용될 수 있는 효과가 있다.Therefore, it is possible to produce a detailed frequency according to the purpose of use, and the circuit is simple and can be easily applied to any circuit.
