ADV7802 Block Diagram Simultaneous interlaced and progressive parallel output for GENERAL DESCRIPTION 525i/525p and 625i/625p 1 525p/625p component progressive scan support The ADV7802 is a high quality, single-chip, multiformat 3D comb 720p/1080i/1080p component HDTV support filter, video decoder, and graphics digitizer. This multiformat 3D Digitizes RGB graphics with maximum pixel clock rate of comb filter decoder supports the conversion of PAL, NTSC, and 135 MHz (ADV7802BSTZ-150 model only) SECAM standards in the form of a composite or an S-video into 24-bit digital input port supports data from DVI/HDMI Rx IC a digital ITU-R BT.656 format. The ADV7802 also supports the Any-to-any, advanced 3 3 color space conversion matrix decoding of a component RGB/YPrPb video signal into a digital Flexible output pixel interface supporting 8-/10-/12-/16-/ YCrCb or RGB pixel output stream. 20-/24-/30-/36-bit SDR/DDR 4:2:2/4:4:4 data formats The support for component video includes standards such as 525i, Programmable interrupt request output pin 625i, 525p, 625p, 720p, 1080i, 1080p, and many other HD and APPLICATIONS SMPTE standards. Graphics digitization is supported by the ADV7802 it is capable of digitizing RGB graphics signals from AV receivers VGA to SXGA rates and converting them into a digital RGB or LCD HDTVs YCrCb pixel output stream. SCART and overlay functionality are PDP HDTVs enabled by the ability of the ADV7802 to simultaneously process CRT HDTVs CVBS and standard definition RGB signals. HDTV STBs with PVR DVD recorders with progressive scan input support The ADV7802 contains two main processing sections. The first Projectors section is the standard definition processor (SDP), which processes all PAL, NTSC, SECAM, and component (up to 525p/625p) signal types. The second section is the component processor (CP), which processes YPrPb and RGB component formats, including RGB graphics. 1 Protected by U.S. Patent Number 4,907,093 and other intellectual property rights.
