DESCRIPTION
The LZ0P3641/42∫/45∫/46 are 1/4-type (4.5 mm) 350 000-pixel built-in lens color CCD (charge­coupled device) area sensors. All pixel signals can 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.

NOTES :
1. Do not connect to DC voltage directly. When OFD is connected to GND, connect VOD to GND. Overflow drain clock is applied below 27 Vp-p.
2. Do not connect to DC voltage directly. When Ø
RS is connected to GND, connect VOD to GND. Reset gate clock is
applied below 8 Vp-p.
3. When clock width is below 10 µs, and clock duty factor is below 0.1%, voltage difference between vertical clocks will be below 28 V.

NOTES :
1. Use the circuit parameter indicated in "SYSTEM CONFIGURATION EXAMPLE", and do not connect to DC voltage directly.
2. V
PW is set below VØVL that is low level of vertical shift register clock, or is used with the same power supply that is connected
to V
L of V driver IC.
* To apply power, first connect GND and then turn on V
OD. After turning on VOD, 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, øTake care not to drop the device when
mounting, handling, or transporting.
øAvoid 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.
ø Recommended mounting screw :
Ø1.7 tapping screw (B-tight type), Length, L = the thickness of the circuit board
+ 5 mm
ø Recommended clamp torque : 0.012 N·m
[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,
ø Do not hit the lens. ø Do not give a shock large enough to cause
distortion.
ø 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 counter­clockwise 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 : ø 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.
ø Do not put too much force onto the lens and
the lens holder while soldering.
ø 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.
ø Dust from static electricity should be blown
off with an ionized air blower. For anti­electrostatic measures, however, ground all the leads on the device before blowing off the dust.
ø 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.
ø 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 :
ø Use ESD-measured soldering iron ø 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.
