Data Sheet 12-Bit, Integrated, Multiformat SDTV/HDTV Video Decoder and RGB Graphics Digitizer ADV7403 FEATURES GENERAL DESCRIPTION 4 Noise Shaped Video (NSV)® 12-bit analog-to-digital converters (ADCs) sampling up to 140 MHz (140 MHz speed grade only) Mux with 12 analog input channels SCART fast blank support Internal antialias filters NTSC/PAL/SECAM color standards support 525p/625p component progressive scan support 720p/1080i component HDTV support Digitizes RGB graphics up to 1280 × 1024 at 75 Hz (SXGA) (140 MHz speed grade only) 24-bit digital input port supports data from DVI/HDMI receiver IC Any-to-any, 3 × 3 color-space conversion matrix Industrial temperature range: −40°C to +85°C 12-bit 4:4:4 and 10-/8-bit 4:2:2 DDR pixel output interface Programmable interrupt request output pin Vertical blanking interval (VBI) data slicer, including teletext The ADV7403 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 ADV7403 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 ADV7403; 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 ADV7403 to simultaneously process CVBS and standard definition RGB signals. The fast blank pin controls the mixing of these signals.

B The ADV7403 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.
