3. IC901, IC902 (V Driver) and IC911 (H Driver)
An H driver and V driver are necessary in order to generate
the clocks (vertical transfer clock, horizontal transfer clock
and electronic shutter clock) which driver the CCD.
IC901 and IC902 are V driver. In addition the XV1-XV4 sig-
nals which are output from IC102 are the vertical transfer
clocks, and the XSG signal which is output from IC102 is su-
perimposed onto XV2 and XV3 at IC901 and IC902 in order
to generate a ternary pulse. In addition, the XSUB signal which
is output from IC102 is used as the sweep pulse for the elec-
tronic shutter. A H driver is inside IC911, and H1A, H1B, H2A,
H2B and RG clock are generated at IC911.
