ICX45AL Diagonal 8mm (Type /) Progressive Scan CCD Solid-state Image Sensor with Square Pixel for CCIR B/W Cameras Description The ICX45AL is a diagonal 8mm (Type /) interline CCD solid-state image sensor with a square pixel array suitable for CCIR black-and-white cameras. Progressive scan allows all pixel's signals to be output independently within approximately /50 second. This chip features an electronic shutter with variable charge-storage time which makes it possible to realize full-frame still images without a mechanical shutter. Square pixel makes this device suitable for image input and processing applications. High sensitivity and low dark current are achieved through the adoption of the HAD (Hole-Accumulation Diode) sensors. This chip is suitable for applications such as FA and surveillance cameras. pin DIP (Cer-DIP) Pin Features Progressive scan allows individual readout of the image signals from all pixels.

Center scan mode This is the center scan mode using the progressive scan method. The undesired portions are swept by vertical register high-speed transfer, and the picture center portion is cut out. There are the mode (00 frames/s) which outputs 64 lines of an output line portion, and the mode (00 frames/s) which outputs 88 lines.

ICX45AL Notes on Handling ) Static charge prevention CCD image sensors are easily damaged by static discharge. Before handling be sure to take the following protective measures. a) Either handle bare handed or use non-chargeable gloves, clothes or material. Also use conductive shoes. b) When handling directly use an earth band. c) Install a conductive mat on the floor or working table to prevent the generation of static electricity. d) Ionized air is recommended for discharge when handling CCD image sensor. e) For the shipment of mounted substrates, use boxes treated for the prevention of static charges. ) Soldering a) Make sure the package temperature does not exceed 80 C. b) Solder dipping in a mounting furnace causes damage to the glass and other defects. Use a 0W soldering iron with a ground wire and solder each pin in less than seconds. For repairs and remount, cool sufficiently. c) To dismount an image sensor, do not use a solder suction equipment. When using an electric desoldering tool, use a thermal controller of the zero cross On/Off type and connect it to ground. ) Dust and dirt protection Image sensors are packed and delivered by taking care of protecting its glass plates from harmful dust and dirt. Clean glass plates with the following operation as required, and use them. a) Perform all assembly operations in a clean room (class 000 or less). b) Do not either touch glass plates by hand or have any object come in contact with glass surfaces. Should dirt stick to a glass surface, blow it off with an air blower. (For dirt stuck through static electricity ionized air is recommended.) c) Clean with a cotton bud and ethyl alcohol if the grease stained. Be careful not to scratch the glass. d) Keep in a case to protect from dust and dirt. To prevent dew condensation, preheat or precool when moving to a room with great temperature differences. e) When a protective tape is applied before shipping, just before use remove the tape applied for electrostatic protection. Do not reuse the tape. 4) Installing (attaching) a) Remain within the following limits when applying a static load to the package. Do not apply any load more than 0.7mm inside the outer perimeter of the glass portion, and do not apply any load or impact to limited portions. (This may cause cracks in the package.) Upper ceramic 9N 9N 9N 0.9Nm Lower ceramic Low melting point glass Compressive strength Shearing strength Tensile strength Torsional stregth b) If a load is applied to the entire surface by a hard component, bending stress may be generated and the package may fracture, etc., depending on the flatness of the ceramic portions. Therefore, for installation, use either an elastic load, such as a spring plate, or an adhesive. 9
ICX45AL c) The adhesive may cause the marking on the rear surface to disappear, especially in case the regulated voltage value is indicated on the rear surface. Therefore, the adhesive should not be applied to this area, and indicated values should be transferred to other locations as a precaution. d) The notch of the package is used for directional index, and that can not be used for reference of fixing. In addition, the cover glass and seal resin may overlap with the notch of the package. e) If the leads are bent repeatedly and metal, etc., clash or rub against the package, the dust may be generated by the fragments of resin. f) Acrylate anaerobic adhesives are generally used to attach CCD image sensors. In addition, cyanoacrylate instantaneous adhesives are sometimes used jointly with acrylate anaerobic adhesives. (reference) 5) Others a) Do not expose to strong light (sun rays) for long periods. For continuous using under cruel condition exceeding the normal using condition, consult our company. b) Exposure to high temperature or humidity will affect the characteristics. Accordingly avoid storage or usage in such conditions. c) Brown stains may be seen on the bottom or side of the package. But this does not affect the CCD characteristics. 0
