AK8812集成電路（IC）的編碼器解碼器轉(zhuǎn)換器規(guī)格書PDF中文資料

AK8812屬于集成電路（IC）的編碼器解碼器轉(zhuǎn)換器。由旭化成微電子株式會社制造生產(chǎn)的AK8812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 AK8811 and AK8812 are low voltage, low power and small packaged Digital Video Encoder. They are suitable for a portable DVD or VCD player. They convert ITU-R.BT601/656 standard 8- bit parallel data into analog composite video, S-Video or analog component signals Y/Cb/Cr in NTSC and PAL formats.
