摘　　要：AD9042AST是美国AD公司推出的1种高速度、高性能、低功耗的12位模数转换器,主要针对的是需要高速数据采集和高速密集数据处理的应用场合,例如视频信号处理、蜂窝电话及个人通信业务(PCS)、全球定位系统(GPS)、频谱分析仪、光电器件、医学图像处理等。本文详细介绍AD9042AST的性能特点、内部结构、引脚定义、编码及设计中应注意的问题。The AD9042AST is a high speed, high performance, low power 12-bit analog-to-digital convener of analog devices instrument in U. S. A, and it mainly aims at the applications, which needs high speed data gathering and dense data processing, such as video signal processing, celluar/PCS, GPS anti-jamming receivers, spectrum analyzers, electro-optics, medical imaging and so on. This paper introduces in detail the performance, internal structure, pin descriptions, encoding and some problems, which users should pay attention to.
