Overview
The ADV7401BSTZ-80, 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 into a digital ITU-R BT.656 format. It also decodes component RGB/YPrPb video signals into digital YCrCb or RGB pixel output streams. The ADV7401 is designed to handle a wide range of component video standards such as 525i, 625i, 525p, 625p, 720p, 1080i, and other HD and SMPTE standards. Additionally, it can digitize RGB graphics signals from VGA to SXGA rates and convert them into digital RGB or YCrCb pixel output streams.
