Overview
The ADV7281WBCPZ-M, produced by Analog Devices Inc., is a versatile one-chip, multiformat video decoder. This device automatically detects standard analog baseband video signals compatible with worldwide NTSC, PAL, and SECAM standards in the form of composite, S-Video, and component video. It converts these analog video signals into an 8-bit YCrCb 4:2:2 video data stream, which is output over a mobile industry processor interface (MIPI®) CSI-2 interface. The ADV7281WBCPZ-M is particularly suited for applications requiring multiple video input channels and advanced video processing features.
