AK8817集成電路（IC）的編碼器解碼器轉換器規(guī)格書PDF中文資料

AK8817屬于集成電路（IC）的編碼器解碼器轉換器。由旭化成微電子株式會社制造生產的AK8817編碼器，解碼器，轉換器該系列產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制過程。示例包括從數(shù)字數(shù)據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 AK8817/18 is a Digital Video Encoder for Portable and Mobile application. ITU-R BT.601 level compatible Y, Cb,and Cr signals which correspond to 27MHz or square pixel are encoded into either NTSC or PAL compatible composite video signal. Interface is made in HSYNC-, VSYNC- synchronized slave-mode operation or ITU-R.Bt656. AK8817/18 has 75ohm driver with LPF.

It is possible to encode the VBID(CGMS-A) and WSS signal on the output video signal. Host Control interface is I2C Bus I/F.
