Interface Circuit
1
BIAS
ADC bias pin
Connect a 0.01-F capacitor between this pin and pin 5
(VSS1).
1.3
2
VRT
ADC bias pin
Sets upper limit of range D for ADC.
Connect a 0.01-F capacitor between this pin and pin 5
(VSS1).
The output voltage is held at internal level.
3.16
3
VDD1
ADC power supply pin (analog)
Apply the same voltage as that of pin 23 (VDD2).
5.0
Internally connected to pin 23 (VDD2).
4
CIN
Chrominance signal input pin
(I2C Bus function: NR)
Because the signal is internally center-biased, it should
be applied after cutting the DC component using a
capacitor of around 0.01 F.
2.5
5
VSS1
ADC GND pin (analog)
Set the same voltage as that of pin 26 (VSS2).
0.0
Internally connected to pin 26 (VDD2).
6
VRB
ADC bias pin
Sets lower limit of range D for ADC.
Connect a 0.01-F capacitor between this pin and pin 5
(VSS1).
The output voltage is held at internal level.
1.83
7
YIN
Luminance signal input pin
(I
2C Bus function: NR)
Because sync tip clamp is internally used, the signal
should be applied after cutting the DC component
using a capacitor of around 0.47 F.
Sync Tip
NR Mode
: 1.86
YCS Mode
: 1.83
8
TEST
Pin for reset control and test control when shipping.
Reset control: Applying pulse of 10 s or longer while
the pin is at High with power on resets all the I
2C bus
settings to 0. For normal use, set the pin to Low.
