CCD Drive Clock Generator Circuit

This circuit is also contained in IC17 (UF-585: IC7). Its function is to generate FSG, FCK1, FCK2 and RS clock signals, which are
required for driving the CCD. These clock signals are generated by the system clock generator circuit derived from the 4 MHz clock
signal that is input to IC9 (UF-585: IC7). Its timing chart is shown below.The FR clock supplied to the CCD is output from the RS of
IC2 (PEGASUS). The RS clock of IC2 is derived from the FR clock of IC17 [MN86075] (UF-595: IC7 [MN86074]) generates the
timing of the RS clock to drive the CCD.
