Voltage on 1V2-1V8 (DVDD)
Jumper Configuration
1.8
V
If none of the described voltage levels is suitable for the used camera: custom voltages in the
range from 1.2
V to 3.3 V can be configured by using resistors instead of jumpers for connecting
the pins.
The output voltage can be determined by formula
•
R
is the resistance that results from the applied circuit (see equation
•
R
left
is the resistance of the left
•
R
right
is the one of the right jumper replacement

The following figure shows the circuit.
Pin header “1V2-1V8” is called “X8” in the circuit diagram.
The relation between the pin header orientation in the schematic and on the board is also
illustrated.
