Overview
The ADV7343BSTZ, produced by Analog Devices Inc., is a high-speed digital-to-analog video encoder. It is housed in a 64-lead LQFP package and features six high-speed, 3.3 V, 11-bit video DACs. These DACs support various video formats including composite (CVBS), S-Video (Y-C), and component (YPrPb/RGB) in standard definition (SD), enhanced definition (ED), and high definition (HD). The device has a 24-bit pixel input port that can be configured in multiple ways, supporting both YCrCb and RGB color spaces. It also includes embedded EAV/SAV timing codes and supports SDR and DDR input modes.
