ADV7189B屬于集成電路（IC）的編碼器解碼器轉(zhuǎn)換器。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的ADV7189B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）；以及便于將標準 UART 連接到標準紅外收發(fā)器的器件。

GENERAL DESCRIPTION

The ADV7189B integrated video decoder automatically detects and converts a standard analog baseband television signal, compatible with worldwide standards NTSC, PAL, and SECAM into

4:2:2 component video data-compatible with 20-, 16-, 10-, and 8-bit CCIR601/CCIR656.
