Figure 15. Black Level Offset Calibration Block Diagram
To get the maximum color resolution and dynamic range,
the XRD98L59 uses a digitally controlled feedback cir-
cuit to correct for offset in the CCD signal as well as offset
in the CDS, PGA & ADC signal path. This calibration is
done while the CCD outputs Optical Black (OB) pixels.
The CAL input signal is used to define when the CCD
output contains OB pixels. The calibration logic will take
into account the internal pipeline delay.
