AK8815/16
NTSC/PAL Digital Video Encoder

GENERAL DESCRIPTION

The AK8815/16 is a digital video encoder which is developed for portable apparatus applications such as cellular
phone etc.. ITU-R BT.601 level compatible Y, Cb,and Cr signals which correspond to square pixel are encoded
into either NTSC or PAL compatible composite video signal. Interface is made in HSYNC-, VSYNC- synchronized
slave-mode operation. It is controlled via a 4-wire serial interface.
