ADV7343屬于集成電路（IC）的編碼器解碼器轉(zhuǎn)換器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADV7343編碼器，解碼器，轉(zhuǎn)換器該系列產(chǎn)品可用于將信息封裝或編碼為適合于傳輸或存儲的格式，和/或在通信路徑的另一端執(zhí)行逆運算，通常是通過使用某些形式的調(diào)制過程。示例包括從數(shù)字數(shù)據(jù)生成模擬視頻信號的器件（反之亦然）；基于傳輸目的對按鈕的狀態(tài)進行編碼的器件（實現(xiàn)遠程控制功能）；以及便于將標(biāo)準 UART 連接到標(biāo)準紅外收發(fā)器的器件。

GENERAL DESCRIPTION

The ADV7342/ADV7343 are high speed, digital-to-analog video encoders in a 64-lead LQFP package. Six high speed, 3.3 V, 11-bit video DACs provide support for composite (CVBS), S Video (Y/C), and component (YPrPb/RGB) analog outputs in either standard definition (SD), enhanced definition (ED), or high definition (HD) video formats.

The ADV7342/ADV7343 each have a 24-bit pixel input port that can be configured in a variety of ways. SD video formats are supported over a SDR interface and ED/HD video formats are supported over SDR and DDR interfaces. Pixel data can be supplied in either the YCrCb or RGB color spaces.
