AK8813/14
NTSC/PAL Digital Video Encoder
GENERAL DESCRIPTION
The AK8813/14 is low voltage, low power and small packaged Digital Video Encoder. It is suitable
for a STB or Digital TV. It converts ITU-R.BT601/656 standard 8- bit parallel data into analog
composite video signal, S-video in NTSC and PAL formats.
AK8813/14 supports Copy protection, Closed Captioning and Video Blanking ID(CGMS-A) and WSS.
These functions are controlled by high-speed I
2
C Bus interface.

I
27MHz 8-Bit 4:2:2 multiplexed Y,Cb,Cr Data Input.
For Rec.656 format, AK8813/14 decodes EAV.
For non-Rec.656 format (without EAV), AK8813/14 operates in Master or
Slave mode.
12-13 TEST
I Test pin. Ground for normal operation
14 SELA

SDA I/O
Serial interface data
17 PD
I Power Down Pin. After returning from PD mode to normal operation,
RESET Sequence should be done to AK8813/14.
18 /RESET
I
After this pin becomes "L", AK8813/14 starts the internal initializing
sequence.
After initializing sequence, AK8813/14 is set NTSC mode, Rec.656
decoding mode. All DACs Off condition.
After power up, AK8813/14 must be initialized with this pin.
(27MHz Clock is necessary for reset sequence.)
