VHIGH_ADC
Input
High reference voltage of internal ADC. Nominal input range of the ADC
is between 2V and 4V. The resistance between VLOW_ADC and
VHIGH_ADC is about 1.5 k
.
Connect with 1k 1
to VDDA and decouple with 100 nF to GND.
63
GND_ADC_ANA
Ground
Analog ground of the ADC circuitry.
64
VDD_ADC_ANA
Supply
Analog supply of the ADC circuitry (typical 5V).
65
VDD_ADC_DIG
Supply
Digital supply of the ADC circuitry (typical 5V).
66
GND_ADC_DIG
Output
Digital ground of the ADC circuitry.
67
VDD_DIG_OUT
Supply
Power supply of ADC digital output. Connect to 5V for normal operation.
Can be brought to lower voltage when image sensor must be interfaced
to low voltage periphery.

VDDA
Supply
Analog supply of the image core (typical 5V).
74
GNDA
Ground
Analog ground of the image core (typical 5V).
75
GND_AB
Supply
Anti-blooming drain control voltage. Default: connect to ground where the
anti-blooming is operational but not maximal. Apply 1V DC for improved
anti-blooming.
76
VREF
Supply
Analog supply. Reset level for RESET_DS. Is used for extended optical
dynamic range. See FAQ for more details.
77
VRES
Supply
Analog supply. Reset level for RESET (typical 5V).

Pin Description
Notes
1. All pins with the same name can be connected together.
2. Unused inputs must always be tied to an appropriate level, e.g., VDD or GND.
3. Note on power up behavior: At power on, the image sensor is in an undefined state. It is advised that after start up an address is latched as soon as possible
into the Y- decoder and the X- decoder to prevent high current consumption.
4. There is no on-chip power supply rejection. This means that every noise signal on the analog supply voltages is copied directly to the analog video signal
(decoupling of the supply voltages as close as possible to the image sensor is recommended).
