1. DESCRIPTION

The ADV7403BSTZ-110 is a high quality, single chip, multiformat video decoder and graphics digitizer. This multiformat decoder supports the conversion of PAL, NTSC, and SECAM standards in the form of composite or S-Video into a digital ITU-R BT.656 format. The ADV7403BSTZ-110 also supports the decoding of a component RGB/YPrPb video signal into a digital YCrCb or RGB pixel output stream. The support for component video includes standards such as 525i, 625i, 525p, 625p, 720p, 1080i, 1250i, and many other HD and SMPTE standards. Graphic digitization is also supported by the ADV7403BSTZ-110; it is capable of digitizing RGB graphics signals from VGA to SXGA rates and converting them into a digital RGB or YCrCb pixel output stream. SCART and overlay functionality are enabled by the ability of the ADV7403BSTZ-110 to simultaneously process CVBS and standard definition RGB signals. The fast blank pin controls the mixing of these signals. The ADV7403BSTZ-110 contains two main processing sections. The first is the standard definition processor (SDP), which processes all PAL, NTSC, and SECAM signal types, and the second is the component processor (CP), which processes YPrPb and RGB component formats, including RGB graphics. For additional descriptions of the features of the ADV7403BSTZ-110, see the Functional Overview and the Theory of Operation sections.
