10-Bit, Integrated, Multiformat SDTV/HDTV Video Decoder and RGB Graphics Digitizer ADV7401 FEATURES GENERAL DESCRIPTION Four 10-bit ADCs sampling up to 140 MHz The ADV7401 is a high quality, single chip, multiformat video (140 MHz speed grade only) decoder and graphics digitizer. This multiformat decoder 12 analog input channel mux supports the conversion of PAL, NTSC, and SECAM standards SCART fast blank support in the form of composite or S-video into a digital ITU-R BT.656 Internal antialias filters format. The ADV7401 also supports the decoding of a NTSC/PAL/SECAM color standards support component RGB/YPrPb video signal into a digital YCrCb or 525p-/625p-component progressive scan support RGB pixel output stream. The support for component video 720p-/1080i-component HDTV support includes standards such as 525i, 625i, 525p, 625p, 720p, 1080i, Digitizes RGB graphics up to 1280 1024 75 Hz (SXGA) 1250i, and many other HD and SMPTE standards. Graphic (140 MHz speed grade only) digitization is also supported by the ADV7401 it is capable of 24-bit digital input port supports data from DVI/HDMI Rx IC digitizing RGB graphics signals from VGA to SXGA rates and Any-to-any, 3 3 color-space conversion matrix converting them into a digital RGB or YCrCb pixel output Industrial temperature range (40C to +85C) stream. SCART and overlay functionality are enabled by the 12-bit 4:4:4/8-bit 4:2:2 DDR pixel output interface ADV7401s ability to simultaneously process CVBS and Programmable interrupt request output pin standard definition RGB signals. The mixing of these signals is VBI data slicer (including teletext) controlled by the fast blank pin. The ADV7401 contains two main processing sections. The first APPLICATIONS is the standard definition processor (SDP), which processes all LCD/DLP rear projection HDTVs PAL, NTSC, and SECAM signal types. The second is the PDP HDTVs component processor (CP), which processes YPrPb and RGB CRT HDTVs component formats, including RGB graphics. For more specific LCD/DLP front projectors descriptions of the ADV7401 features, see the Detailed LCD TV (HDTV ready) Functionality and Detailed Description sections.
