IC934, IC935 (V Driver) and IC931 (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.IC934 and IC935 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 IC934 andIC935 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 IC931,and H1, H2 and RG clock are generated at IC931.4. IC931 (CDS, AGC Circuit and A/D Converter)The video signal which is output from the CCD is input to Pin(29) of IC931. 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 (37) of IC911. The video signal iscarried out A/D converter, and is output by 10-bit.Fig. 1-2.
