Overview
The ADV7281WBCPZ-MA, 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. The ADV7281WBCPZ-MA 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. This decoder is fabricated in a 1.8 V CMOS process and is packaged in a 32-lead LFCSP (5mm x 5mm x 0.75mm with exposed pad), making it ideal for space-constrained and automotive applications due to its operating temperature range of -40°C to +105°C.
