ASAHI KASEI [AK8815/16] www.DataSheet4U.com 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 inter.
