Abstract

본 발명은 외부로부터 입력되는 데이타를 처리하기 위한 동기신호를 발생하기 위한 동기신호 발생장치에 관한 것으로, 입력데이타에 포함된 동기용데이타를 검출하기 위한 동기검출부와, 동기검출부로부터의 펄스신호에 의하여 리세트되고 내부 클럭을 카운트하여 바이트클럭과 워드클럭을 발생하는 워드카운터와, 워드클럭을 카운트하여 블럭을 표시하는 신호를 발생하는 블럭카운터와, 상기 각 부들로부터 외부 동기 또는 내부 동기신호를 공급받아 입력데이타를 처리하기 위한 동기신호를 출력하는 동기신호발생부를 구비하여, 입력데이타에 동기용데이타가 있는 경우 이를 검출하여 외부 동기에 맞는 동기신호를 발생하고, 입력데이타에 동기용데이타가 없거나 이상이 있는 경우에는 내부 클럭을 카운트하여 데이타처리에 필요한 동기신호를 발생한다.The present invention relates to a synchronization signal generating device for generating a synchronization signal for processing data input from the outside, and comprising a synchronization detection unit for detecting synchronization data included in input data and a pulse signal from the synchronization detection unit. A word counter that is reset and counts an internal clock to generate a byte clock and a word clock, a block counter that generates a signal to count a word clock and displays a block, and receives an external sync or an internal sync signal from the respective parts Synchronization signal generating unit for outputting synchronization signal for processing input data, and if there is synchronization data in input data, it detects it and generates synchronization signal suitable for external synchronization. If present, the internal clock is counted to obtain a synchronization signal for data processing. The lives.
