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.

PIN FUNCTIONAL DESCRIPTION (preliminary)
No. Pin Name I/O Function Quartz crystal resonator connection pin ( to be grounded via a 18 pF capacitor as shown in the recommended circuit ). NTSC: 24.5454 MHz / PAL: 29.50 MHz Hi-Z input is acceptable to this pin at PDN = L. Input from an external crystal oscillator should be connected to this pin. Quartz crystal resonator connection pin ( to be grounded via a 22 pF capacitor as shown in the recommended circuit ). NTSC: 25..
