Overview
The ADV7280AWBCPZ, produced by Analog Devices Inc., is a versatile one-chip, multiformat video decoder designed to automatically detect and convert standard analog baseband video signals into YCrCb 4:2:2 component video data streams. This device supports various video formats including composite (CVBS), S-Video (Y/C), and component (YPrPb) video, and it can autodetect NTSC, PAL, and SECAM standards. The ADV7280AWBCPZ features a 10-bit analog-to-digital converter (ADC) with 4× oversampling per channel, ensuring high-quality video conversion. It is available in two variants: the ADV7280A with up to 4 input channels and the ADV7280A-M with up to 8 input channels. The device is packaged in a 32-lead LFCSP (Lead Frame Chip Scale Package) and is RoHS compliant, making it suitable for automotive, industrial, and consumer applications.
