随着电视技术的不断发展,它已在国民经济各个领域中得到广泛的应用。为保证电视图象的质量,应努力提高同步机的稳定性与可靠性。同步机的数字集成化将进一步减小设备的体积和重量,提高设备的稳定性和可靠性。本文对PMOS中规模数字集成彩色电视同步机的设计考虑作了综述,同时,介绍了其中部分电路的逻辑设计方法。 With the continuous development of television technology, it has been widely used in various fields of the national economy. In order to ensure the quality of television images, efforts should be made to improve the stability and reliability of the synchronous machine. The digital integration of the synchronous machine will further reduce the size and weight of the equipment and improve the stability and reliability of the equipment. In this paper, the design consideration of the digital integrated color TV synchronous machine in PMOS is reviewed. At the same time, the logic design method of some of the circuits is introduced.
