Abstract

본 발명은 통신 장치에서 사용되는 클록의 장애를 검출하기에 적합한 클록 장애 검출 장치에 관한 것으로, 종래에는 클록에 장애가 발생하면 통신 장치의 기능이 마비되는 등 통신 장치의 대부분의 기능에 심각한 장애가 초래되었으나, 본 발병에서는 디지탈 회로를 사용하는 통신 장치 등에서 사용하는 클록에 장애가 발생할 경우 이를 검출하여 프로세서 등의 해당 제어부측에 알려주어 적합한 조치가 이루어지도록 함으로써 상기 결점을 개선시킬 수 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clock failure detection device suitable for detecting a failure of a clock used in a communication device. In the related art, when a failure occurs in a clock, a serious failure occurs in most functions of the communication device, such as paralyzing the function of the communication device. In this case, the fault can be improved by detecting a failure in a clock used in a communication device using a digital circuit, and informing a corresponding control unit such as a processor so that appropriate measures can be taken.
