【摘要】 随着电子技术的发展和数字化程度的提高,峰窝电话、数码相机、DVD／HPTV和多媒体等数码产品得到了广泛的应用。但若要显示这些视频信号,就必须将其转换成模拟RGB／YpbPr信号并进行放大。通过对新型视频芯片ISL59830的性能特点、引脚功能和工作原理等的介绍,给出了该芯片一种典型的应用电路。该芯片性能优良、外围电路简单,可广泛应用于各种显示设备的视频驱动电路中。更多还原

【Abstract】 Following the rapid development of digitization, digital multimedia products, e.g. cellular phones, digital cameras, and DVD/HPTV, etc., have been widely used. While in order to display the video signal, it is necessary to convert it into analog RGB/YPbPr signal and amplify. A new video chip ISL59830 is introduced. The features, functions of pins and operational principle are presented. In addition, a typical application circuit is given. The chip offers excellent performance, simple peripheral circuit and can be used in video driver circuits of various display equipment.更多还原
