AK8817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(huì)社制造生產(chǎn)的AK8817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(chǔ)的格式，和/或在通信路徑的另一端執(zhí)行逆運(yùn)算，通常是通過(guò)使用某些形式的調(diào)制過(guò)程。示例包括從數(shù)字?jǐn)?shù)據(jù)生成模擬視頻信號(hào)的器件（反之亦然）；基于傳輸目的對(duì)按鈕的狀態(tài)進(jìn)行編碼的器件（實(shí)現(xiàn)遠(yuǎn)程控制功能）；以及便于將標(biāo)準(zhǔn) UART 連接到標(biāo)準(zhǔn)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.
