Usage Notes
Power supply application timing
When applying power to the LC89902V, either both power-supply voltages must be turned on at the same time or V
CC
(+5 V) must be turned on before V
EE
(10 V) is turned on. The IC may be destroyed if V
EE
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 V
CC
and ground and between V
EE
and ground to eliminate noise
from the power supply lines. These capacitors must have values of at least 47 F.
