IC902, IC903 (V Driver) and IC905 (H driver)An H driver and V driver are necessary in order to generatethe clocks (vertical transfer clock, horizontal transfer clockand electronic shutter clock) which driver the CCD.IC902 and IC903 are V driver. In addition the XV1-XV6 sig-nals which are output from IC101 are the vertical transferclocks, and the XSG signal is superimposed at IC902 andIC903 in order to generate a ternary pulse. In addition, theXSUB signal which is output from IC101 is used as the sweeppulse for the electronic shutter. A H driver is inside IC905,and H1, H2 and RG clock are generated at IC905.4. IC905 (CDS, AGC Circuit and A/D Converter)The video signal which is output from the CCD is input to Pin(27) of IC905. There are inside the sampling hold block, AGCblock and A/D converter block.The setting of sampling phase and AGC amplifier is carriedout by serial data at Pin (32). The video signal is carried outA/D converter, and is output by 12-bit.Fig. 1-2.
