Abstract
Description
Claims (1)
- 발진기(19)를 구비한 데지털 데이터 전송회로에 있어서, 상기 발진기(19)의 출력을 디플립플롭(12,13)의 클럭단(CK)으로 입력되어 소정 각각 분주하는 제1수단(100)과, 상기 제1수단(100)의 디플립플롭(12)의 출력신호를 디플립플롭(14)의 클럭단(CK)으로 입력되어 전송데이터를 래치하는 제2수단(200)과, 상기 제1수단(100) 디플립플롭(13)의 출력신호와 상기 제2수단(200)의 디플립플롭(14)의 출력을 앤드게이트(16)에서 논리곱하여 전송데이터를 결정하는 제3수단(300)과, 상기 제1수단(100)의 디플립플롭(12)의 출력단(Q)의 출력과 디플립플롭(13)의 출력단()의 출력을 앤드게이트(15)에서 앤드하여 전송비트에 따른 듀티 사이클의 비율을 결정하는 제4수단(400)과, 상기 제4수단(400)의 출력을 지연회로(18)에서 지연하여 지터의 영향에 의한 폭을 좁히기 위한 제5수단(500)과, 상기 제3수단(300)과 제5수단(500)의 출력을 오아게이트(17)에서 합하여 PWM데이터로 출력하는 제6수단(600)과, 상기 제6수단(600)의 PWM데이터로부터 전송클럭을 클럭재생회로(25)에서 재생추출하는 제7수단(700)과, 상기 제7수단(700)의 출력을 인버터(21)에서 반전한 후 디플립플롭(24)의 클럭단(CK)으로 입력하여 상기 PWM데이터를 샘플링에 의해 원래 데이터로 디코딩 재생하는 제8수단(800)으로 구성함을 특징으로 하는 PWM코딩/디코딩에 의한 디지털 데이터 전송회로.
