Overview
The ADV7343WBSTZ-RL, produced by Analog Devices Inc., is a high-speed digital-to-analog video encoder. This component is part of the ADV7342/ADV7343 series and is housed in a 64-lead Low Profile Quad Flat Package (LQFP). It features six high-speed, 3.3 V, 11-bit video DACs that support various analog video outputs including composite (CVBS), S-Video (Y/C), and component (YPrPb/RGB) in standard definition (SD), enhanced definition (ED), and high definition (HD) video formats.
The device includes a 24-bit pixel input port that can be configured in multiple ways, supporting SD video formats over SDR interfaces and ED/HD video formats over both SDR and DDR interfaces. It also supports pixel data in YCrCb or RGB color spaces, embedded EAV/SAV timing codes, external video synchronization signals, and the I2C communication protocol.
