Video Encoder
AK8817/18
NTSC/PAL Digital Video Encoder
 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 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.
