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.
FEATURES
• NTSC-M, PAL-B, D, G, H, I encoding
• Composite Video Output
• Y:Cb:Cr 4:2:2 Square Pixel Data Input
• H/V Slave Operation
• Y filtering: 2 x over-sampling
• C filtering: 4 x over-sampling
• 9-bit DAC
• Macrovision Copy Protection Rev. 7.1 * (only AK8815 )
• VBID ( CGMS-A ) Compatible
• WSS Compatible
• On-chip Quartz Crystal Oscillator circuit
• Clock: Square Pixel data rate 24.5454 MHz ( NTSC ), 29.50 MHz ( PAL )
• Device Control I / F : 4- wire Serial Bus Interface
• On-chip Color Bar Output
• Black Burst Output
• Internal Operating Voltage: 2.7 V ~ 3.3 V
• supplying Interface Power Supply ( 1.6 V ~ 2.0 V or 2.7 V ~ 3.3 V )
• Power-down function
• Monolithic CMOS
• 57 pin FBGA ( 5 mm sq ) ( lead-free package )

Before PDN setting ( PDN to low ), Reset must be enabled for a duration of longer-than-100 clock time.
After PDN release ( PDN to high ), Reset must be enabled for 10 mS or longer till analog part reference
voltage & current are stabilized.

at power-down, all control signals must surely be set to either power supply or ground level of the selected power
supply, and not to ViH / ViL levels.
