The IC may be destroyed if VEE is turned on first. • Power supply noise elimination Clock frequency noise may occur on the power supply lines due to the charge and discharge currents required to drive the CCD. Capacitors must be inserted both between VCC and ground and between VEE and ground to eliminate noise from the power supply lines. These capacitors must have values of at least 47 µF.
