– 4 –Fig. 1-3. IC901 Block Diagram3. IC905 (H Driver) and IC901 (V Driver)An H driver and V driver are necessary in order to generatethe clocks (vertical transfer clock, horizontal transfer clock andelectronic shutter clock) which driver the CCD. IC901 is a Vdriver, and the XV1-XV15 signals which are output from IC101are the vertical transfer clocks, and the XSG signal which areoutput is superimposed at IC901 in order to generate a ter-nary pulse. In addition, the XSUB signal which is output fromIC101 is used as the sweep pulse for the electronic shutter. Hdriver has inside IC905 and generate H1, H2, H3 and RGclock at IC905.4. IC905 (CDS, AGC Circuit and A/D Converter)The video signal which is output from the CCD is input to pins(25) of IC905. There are inside the sampling hold block, AGCblock and A/D converter block. Settings of sampling phaseand AGC amplifier is carried out by serial data of pins (32),(33) and (34). The video signal is converted A/D converter,and output to LVDS.Fig. 1-4.
