GENERAL DESCRIPTION
In the CCD configuration the input signal is AC coupled with an external capacitor. An internal clamp sets the black level. In the CIS configuration, the clamp switch can be disabled and the CIS output signal is DC coupled from the CIS sensor to the XRD9824. The CIS signal is level shifted to VRB in order to use the full range of the ADC.
