Overview
The ADV7180WBCPZ, produced by Analog Devices Inc., is a versatile one-chip multiformat video decoder designed to automatically detect and convert standard analog baseband television signals compatible with worldwide NTSC, PAL, and SECAM standards into 4:2:2 component video data compatible with the 8-bit ITU-R BT.656 interface standard. This decoder is fabricated in a 1.8 V CMOS process and features a monolithic CMOS construction, ensuring greater functionality with lower power dissipation. It is particularly suited for space-constrained portable applications due to its LFCSP package options.
