I/O Description
I
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.
I
27MHz Clock Input. The polarity could be inverted by
SYSINV.
I
"L " : data is latched with rising edge.
"H" : data is latched with falling edge.
I 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.
I/O 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.
I/O Rec.656 decode mode : Output
Master mode : Output
Slave mode : Input
I Serial interface clock
I/O Serial interface data
I The slave address is set with this pin.
"L":40H "H":42H
O Output of the Internal Vref. Terminate with 0.1uF or
more capacitor.
I
Input of the Reference Voltage
O
The currents flow this pin adjusts the full-scale
output current of the DAC.
O
Output of Composite Video signal or component U
Output of the C signal or component V
O
O Output of Luminance Signal.
P Analog +3.3V
P Digital +3.3V
G Analog Ground
G Digital Ground
I
Test pin. Ground for normal operation
I/O
