Scanner Repair CG_GS01 - CCD Board − CG_GS01 is linked rigidly with the lens − Monochrome CCD chip − Processing of the control signals (level conversion) for the CCD − Adjustment of the image signals (preamplification) of the CCD for the AD converter on the CG Controller − Setting of the voltages for the black value balance The level of the current supply of the CCD with respect to GND is shifted by means of the SW balance so that an easy activation of the video preamplifiers is possible. The analogue data is transmitted to the CG Controller. The CCD board gets the following control signals from the CG Controller: − Clock (10MHz) − vertical and horizontal synch signals − special signals for the output of the CCD lines Differential line pairs ensure an almost troublefree transmission. The dark current of the CCD can be balanced by means of a black value balance of the CG Controller. To get optimum conditions for the preamplification of the image signals, the whole power supply of the CCD can be shifted. This is achieved via the input of the black value balance.
