8 / 32 page XRD9824 8 Rev. 2.00 THEORY OF OPERATION CIS Configuration (Contact Image Sensor) The XRD9824 has two configurations for CIS applications. Each configuration is set by the control registers accessed through the serial port. Mode 1. DC Coupled If the CIS does not have leading or trailing black pixels as shown in Figure 2, then DC couple the CIS output to the XRD9824 input. Optically Shielded Pixels Valid Pixels Adjust the offset of the CIS (-100 mV to 500 mV) by setting the internal registers of the XRD9824 to set the black pixel value when the LEDs of the CIS are off. When the LEDs are on, use the XRD9824 Programmable Gain to maximize the ADCs dynamic range. Figure 3 shows a typical application for a CIS with an offset of -100mV to 500mV. Figure 2.
