Overview
The ADV7181DBCPZ, produced by Analog Devices Inc., is a high-quality, single-chip, multiformat video decoder and graphics digitizer. This component 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, supporting multiple HD and SMPTE standards. Additionally, it can digitize RGB graphics signals from VGA to XGA rates and convert them into digital DDR RGB or YCrCb pixel output streams.
