3.6.1 ADC timing
The ADC converts the pixel data on the falling edge of the A
clock cycles before this pixel data is at the output of the ADC. This pipeline delay is
shown in Figure 6.
3.6.2 Setting of the ADC reference voltages
The internal resistor R
This results in the values for the external resistors:
