  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.

The standard definition processor(SDP)in the ADV7282Aautomatically detects PAL, NTSC and SECAM standards in theform of composite, S-Video(Y/C)and component. The analogvideo is converted into a 4:2:2 component video data streamthat is output either via an 8-bit ITU-R BT.656 standardcompatibleinterface(ADV7282A)or via a MIPI CSI-2 Tx(hereafter referred to as MIPI Tx) interface (ADV7282A-M).

The ADV7282A also feature a deinterlacer for interlaced toprogressive (I2P) conversion.The ADV7282A offers short to battery (STB) diagnostic senseinputs and general-purpose outputs.
