AC200

Overview

The AC200 is a digital analog mix IC, which use in TV-BOX(H Series) , it is composed of Audio, Video and EPHY modules.

Audio, communicate with SoC through I2s Interface, transform I2S to 2MIC and 1 lineout.

Video, communicate with SoC through CCIR656 Interface, transform CCIR656 to CVBS(Composite Video Broadcast Signal).

EPHY, communicate with SoC through MII/RMII Interface, transform to 100M ethernet.
