Overview
The ADV7180WBCPZ-REEL, produced by Analog Devices Inc., is a versatile 10-bit, oversampling SDTV video decoder. This device automatically detects and converts 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. It features three analog video input channels that accept standard composite, S-video, or component video signals, making it suitable for a wide range of consumer video sources. The ADV7180 is fabricated in a 1.8 V CMOS process and is available in a 40-lead lead frame chip scale package (LFCSP-WQ), ideal for space-constrained and portable applications.
