27MHz 8-Bit 4:2:2 multiplexed Y,Cb,Cr Data Input.
For Rec.656 format, AK8811/12 decodes EAV.
For non-Rec.656 format (without EAV), AK8811/12
operates in Master or Slave mode.
27MHz Clock Input. The polarity could be inverted by
SYSINV.
“L “ : data is latched with rising edge.
“H” : data is latched with falling edge.
After this pin becomes “L”, AK8811/12 starts the
internal initializing sequence.
After initializing sequence, AK8811/12 is set NTSC
mode, Rec.656 decoding mode. All DACs Off
condition.
Either of FID or VSYNC selected by the register.
Rec.656 decode mode :Output
Master mode : Output
Slave mode : Input
FID shows that “L” is odd field and ”H” is even field.
Rec.656 decode mode : Output
Master mode : Output
Slave mode : Input
Serial interface clock

The slave address is set with this pin.
“L”:40H “H”:42H
Output of the Internal Vref. Terminate with 0.1uF or
more capacitor.
