摘　　要：本文叙述单片TA8690AN双制式解码集成电路首次在出口南美彩电机芯上的运用情况。同时对该机芯主要特点、电路组成方框图及原理(功能)、PAL-M·N/NTSC-M制式转换接口电路的设计作了简要的介绍。文中介绍的设计方法可推广应用到其它新型彩电单片机上,其中TA8690AN解码部分的设计也可运用于目前国内广泛生产的PAL(TV)/NTSC(AV)双制式彩电上。In this paper the author narrates the first application of monolithic TA8690AN double -format integrated circuit In the cores of the color television sets exported to South America. Meanwhile, the author makes brief introduction to the principal feature, circuit - forming block diagram and the principle ( function ) of the core, as well as the circuit design of PAL -M · N/NTSC -M format transformation interface. The design method recommended in the paper can find extended application in other new types of monolithic processors of color television sets.and the design of TA8690AN decoding parts can also be applied to the double - format television sets PAL (TV)/NTC (AT) widely produced at home.
