Description :

10-Bit, Integrated, Multiformat SDTV/HDTV Video Decoder and RGB Graphics Digitizer ADV7400A Features Three 10-bit ADCs sampling up to 110 MHz 12 analog input channel mux NTSC/PAL/SECAM color standards support Adaptive digital line length tracking (ADLLT™), signal processing, and enhanced FIFO management give mini TBC functionality 525p/625p component progressive scan support 720p/1080i component HDTV support Digitizes RGB graphics up to 1280 × 1024 @ 60 Hz (SXGA) 24-bit digital input port supports data from DVI/HDMI Rx IC Any-to-any 3 × 3 color-space conversion matrix Industrial temperature range (−40°C to +85°C) 12-bit 4:4:4/8-bit 4:2:2 DDR pixel output interface Programmable interrupt request output pin GENERAL Description The ADV7400A 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 ADV7400A also supports decoding 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 ADV7400A; 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. The ADV7400A contains two main processing sections. The first is the standard definition processor (SDP), which processes all PAL, NTSC, and SECAM signal types. The second is the component processor (CP), which processes YPrPb and RGB component formats, including RGB graphics.
