Overview
The ADV7182WBCPZ, manufactured by Analog Devices Inc., is a 10-bit, standard definition television (SDTV) video decoder with differential inputs. This integrated circuit automatically detects and converts standard analog baseband video signals compatible with worldwide NTSC, PAL, and SECAM standards into a 4:2:2 component video data stream, which is compatible with the 8-bit ITU-R BT.656 interface standard. The decoder supports various video input formats, including composite (CVBS), S-Video (Y/C), and component (YPrPb) video signals, making it versatile for a wide range of consumer and automotive applications.
