Overview
The ADV7180BCPZ, produced by Analog Devices Inc., is a versatile one-chip multiformat video decoder. It automatically detects and converts standard analog baseband television signals compatible with worldwide NTSC, PAL, and SECAM standards into a digital ITU-R BT.656 format. This decoder supports composite, S-Video, and component video inputs, making it suitable for a wide range of consumer video sources. The ADV7180BCPZ is fabricated in a 1.8 V CMOS process, ensuring greater functionality with lower power dissipation, and is available in a 40-lead LFCSP package, ideal for space-constrained portable applications.
