[原创] ADI ADV7282A四路过取样SDTV视频译码解决方案

ADI公司的ADV7282A是10位四路过取样SDTV视频译码器,差分输入,支持NTSC/PAL/SECAM彩色解调,视频输入每路支持CVBS, Y/C和YPrPb模式,模拟视频输入通路配有抗混淆滤波器,NTSC/PAL/SECAM 自动检测,2线I2C兼容串行接口,具有汽车应用的资格和降功耗模式,工作温度−40℃ 到 +105℃ ,主要用在高档驾驶辅助,汽车娱乐系统,媒体播放器和视频安全DVR.本文介绍了ADV7282A主要特性,功能框图,应用电路以及评估板EVAL-ADV7282AEBZ主要特性,连接图和电路图.

The ADV7282A1 has the same pinout as and is softwarecompatible with the ADV7282. The mobile industry processorinterface (MIPIR) model of the ADV7282A (ADV7282A-M)has the same pinout as and is software compatible with theADV7282-M.

All features, functionality, and specifications are shared by theADV7282A and the ADV7282A-M, unless otherwise noted.The ADV7282A is a versatile one-chip, multiformat videodecoder that automatically detects standard analog　basebandvideo signals and converts them into YCrCb 4:2:2 componentvideo data streams.

The analog input of the ADV7282A features an input mux(4-channel on ADV7282A, 6-channel on ADV7282A-M), asingle 10-bit analog-to-digital converter (ADC) and an on-chipdifferential to single-ended converter to accommodate thedirect connection of differential, pseudo differential, or singleendedCVBS without the need for external amplifier circuitry.
