Overview
The ADV7181CWBSTZ-REEL, produced by Analog Devices Inc., is a high-quality, single-chip, multiformat video decoder and graphics digitizer. This integrated circuit supports the conversion of various video standards, including PAL, NTSC, and SECAM, from composite or S-Video formats into digital ITU-R BT.656 format. It also decodes component RGB/YPrPb video signals into digital YCrCb or RGB pixel output streams, supporting a wide range of HD and SMPTE standards. Additionally, the ADV7181C is capable of digitizing RGB graphics signals from VGA to XGA rates and converting them into digital DDR RGB or YCrCb pixel output streams.
