CCD Drive Clock Generator Circuit

This circuit is also contained in IC9. Its function is to generate FSG, FCK1 and FR clock signals, which are required for driving the
CCD. These clock signals are generated by the system clock generator circuit derived from the 25.0 MHz clock signal that is input
to IC160. Its timing chart is shown below.The FSG, FCK1, FCK2, FR and FSH clock supplied to the CCD is output from the OFSG,
OFCK1, OFCK2, FR and FSH of IC40 (DZZAC000108). These clocks of IC40 are derived from the FSG, FCK1, and FR clock of
IC160 (MN86075) generates the timing of the FSG, FCK1, FCK2, FR and FSH clock to drive the CCD.
