ADV7401

GENERAL DESCRIPTION

The ADV7401 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 ADV7401 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 ADV7401; 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 ADV7401’s ability to simultaneously process CVBS and standard definition RGB signals. The mixing of these signals is controlled by the fast blank pin.

The ADV7401 contains two main processing sections. The first

standard definition processor (SDP), which processes all

is the PAL, NTSC, and SECAM signal types. The second is the component processor (CP), which processes YPrPb and RGB component formats, including RGB graphics. For more specific descriptions of the ADV7401 features, see the Detailed Functionality and Detailed Description sections.
