Simplified Functional Block Diagram 525i/525p and 625i/625p GENERAL DESCRIPTION 525p/625p component progressive scan support 1 720p/1080i/1080p component HDTV support The ADV7800 is a high quality, single-chip, multiformat 3D Digitizes RGB graphics with maximum pixel clock rate comb filter, video decoder, and graphics digitizer. This multi- of 150 MHz (150 MHz speed grade only) format 3D comb filter decoder supports the conversion of PAL, 24-bit digital input port supports data from DVI/HDMI Rx IC NTSC, and SECAM standards in the form of a composite or an Any-to-any, advanced 3 3 color space conversion matrix S-Video into a digital ITU-R BT.656 format. The ADV7800 also Flexible output pixel interface supporting 8-/10-/16-/ supports the decoding of a component RGB/YPrPb video signal 20-/24-/30-bit SDR/DDR 4:2:2/4:4:4 data formats into a digital YCrCb or RGB pixel output stream. Programmable interrupt request output pin The support for component video includes standards such as APPLICATIONS 525i, 625i, 525p, 625p, 720p, 1080i, 1080p, and many other HD and SMPTE standards. Graphics digitization is supported by AV receivers the ADV7800 it is capable of digitizing RGB graphics signals LCD HDTVs from VGA to SXGA rates and converting them into a digital PDP HDTVs RGB or YCrCb pixel output stream. SCART and overlay CRT HDTVs functionality are enabled by the ability of the ADV7800 to HDTV STBs with PVR simultaneously process CVBS and standard definition RGB DVD recorders with progressive scan input support signals. Projectors The ADV7800 contains two main processing sections. The first 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.
