2004/Oct
PIN/FUNCTION
48pin LQFP
No.
Pin Name
I/O
Description
1
UD9
I/O
Test pin. Open for normal operation
2-5,
8-11
D7 - D0
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
I
The slave address is set with this pin.
“L”:40H “H”:42H
15
SCL
I
Serial interface clock
16
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.)
20
Y
O
Output of Luminance Signal.
22
C
O
Output of the Chrominance signal
24
COMPOSITE
O
Output of Composite Video signal
27
VREFOUT
O
Output of the Internal Vref. Terminate with 0.1uF or more capacitor.
28
VREFIN
I
Input of the Reference Voltage
29
IREF
O
The currents flow this pin adjusts the full-scale output current of the DAC.
Connect this pin to Analog ground via a 6.8kohm resistor ( better than +/-
1% accuracy ).
32-39
UD0-UD7
I/O
Test pin. Open for normal operation
41
SYSCLK
I
27MHz Clock Input. The polarity could be inverted by SYSINV.
43
UD8
I/O
Test pin. Open for normal operation
45
FID
/VSYNC
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.
46
HSYNC
I/O
Rec.656 decode mode : Output
Master mode : Output
Slave mode : Input
48
SYSINV
I
“L “ : data is latched with rising edge.
“H” : data is latched with falling edge.
