DESCRIPTION
The LZ0P3641/42
/45
/46 are 1/4-type (4.5 mm)
350 000-pixel built-in lens color CCD (charge-

be read independently via the vertical shift register
and horizontal shift register. With their small lens
and WLCC-type flat package, it is possible to make
ultra small color camera easily.

that is low level of vertical shift register clock, or is used with the same power supply that is connected
to V

of V driver IC.
* To apply power, first connect GND and then turn on V

. After turning on V
OD
, turn on PW first and then turn on other powers
and pulses. Do not connect the device to or disconnect it from the plug socket while power is being applied.

NOTES :
1. The average output voltage of G signal in the central
area (H/10, V/10) under uniform illumination.
The standard exposure conditions are defined as when
V
O
is 150 mV.
2. The average output voltage of G signal in the central
area (H/10, V/10) under 10 times exposure of the
standard exposure conditions.
3. The average output voltage of G signal in the central
area (H/10, V/10) when a 1 000 lux light source with a
white board of 90% reflector is imaged.
4. The resolution in the central area (H/10, V/10) at which
the image of the TV resolution chart (ex. EIAJ test chart)
can be distinguished on the B/W video monitor when
converted into composite video signals.
5. The resolution in the peripheral area (image height : Y =
0.8) under the conditions mentioned above.
6. Defined by the following formula at the brightness of
standard output voltage : (Vco/Vce) x 100 [%]
Vco : Output voltage at edge of the image (at NTSC
video output).
Vce : Output voltage at center of the image (at NTSC
video output).
7. The difference between the center position of image and
that of the monitor. This is the ratio for the horizontal
underscanning monitor size which includes the decentering
eccentricity when turning the lens head one time.

PRECAUTIONS FOR BUILT-IN LENS CCD
AREA SENSORS
1. Package Breakage
In order to prevent the package, the lens holder,
and the lens from being broken, follow the
instructions below :
1) The CCD is a precise optical component and
the package-base material is ceramic.
Therefore,
Take care not to drop the device when
mounting, handling, or transporting.
Avoid giving a shock to the package.
Especially when leads are fixed to the socket
or the circuit board, a small shock could
break the package more easily than when the
package isn't fixed.
2) When adjusting the focus, screw the lens holder
to the circuit board before soldering the leads.
At that time, make sure to use a circuit board
with plenty of strength, and to avoid the
package and the lens holder from being broken,
the following screw and clamp torque are
recommended.
Recommended mounting screw :
1.7 tapping screw (B-tight type),
Length, L = the thickness of the circuit board
+ 5 mm
Recommended clamp torque : 0.012 Nm
[however, when the thickness of the circuit
board is thinner than t = 2.0 mm]
3) If any damage or breakage occurs on the
surface of the lens, its characteristics could
deteriorate.
Therefore,
Do not hit the lens.
Do not give a shock large enough to cause
distortion.
Do not scrub or scratch the surface of the
lens.
Even a soft cloth or applicator, if dry, could
cause dust to scratch the lens.
2. Electrostatic Damage
As compared with general MOS-LSI, CCD has
lower ESD. Therefore, take the following anti-static
measures when handling the CCD :
1) Always discharge static electricity by grounding
the human body and the instrument to be used.
To ground the human body, provide resistance
of about 1 M$ between the human body and
the ground to be on the safe side.
2) When directly handling the device with the
fingers, hold the lens holder and do not touch
the lead.
3) To avoid generating static electricity,
a. do not scrub the device with cloth or plastic.
b. do not attach any tape or labels.
c. do not clean the device with dust-cleaning
tape.
4) When storing or transporting the device, put it in
a container of conductive material.
3. Dust and Contamination
Dust or contamination on the surface of the lens
and the inside of the lens holder could deteriorate
the output characteristics or cause a scar. In order
to minimize dust or contamination on the device,
take the following precautions :
1) Do not remove the lens from the body.
Especially when adjusting macro, be careful not
to remove the lens by turning it counter-
clockwise too much.
2) Do not touch the surface of the lens with the
fingers. If dust or contamination gets on the
surface of the lens, the following cleaning
method is recommended :
Handle the built-in lens CCD in a clean
environment such as a cleaned booth. (The
cleanliness level should be, if possible, class
1 000 at least.)
In case where the soldering may exceed the
time mentioned above, resume the work
after the device returns to normal
temperature.
Do not put too much force onto the lens and
the lens holder while soldering.
Be careful not to let the soldering iron touch
the lens holder.
Soldering can be quickly/neatly done by
laying the soldering iron so it lightly touches
the border between the package and the
circuit board and sliding it in sideways.
2) There is no guarantee of the performance of
the device which has been removed or
resoldered after being soldered once under the
conditions mentioned above.
In case there seems to be an inferior device,
consult with our sales office before removing
it.
3) Avoid using or storing the CCD at high
temperature or high humidity as it is a precise
optical component. Do not give a mechanical
shock to the CCD.
4) Do not expose the device to strong light. For
the color device, long exposure to strong light
will fade the color of the color filters.
Dust from static electricity should be blown
off with an ionized air blower. For anti-
electrostatic measures, however, ground all
the leads on the device before blowing off
the dust.
The contamination on the surface of the lens
should be wiped off with a clean applicator
soaked in isopropyl alcohol. Wipe slowly and
gently in one direction only.
Frequently replace the applicator and do not
use the same applicator to clean more than
one device.
Make sure there is no dust or contamination
on the lens and screw it on the lens holder.
4. Other
1) Soldering should be manually performed under
the following conditions :
Use ESD-measured soldering iron
The conditions of the soldering time in which
the soldering iron touches the package,
differs by the shape and the temperature of
the iron end. Refer to the table below and
take great care in soldering.
