| ICX285AL Diagonal 11 mm (Type 2/3) Progressive Scan CCD Image Sensor with Square Pixel for B/W Cameras Description The ICX285AL is a diagonal 11 mm (Type 2/3) interline CCD solid-state image sensor with a square pixel array. High sensitivity and low smear are achieved through the adoption of EXview HAD CCD technology. Progressive scan allows all pixel's signals to be output independently within approximately 1/15 second. Also, the adoption of high frame rate readout mode supports 60 frames per 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. This chip is suitable for image input applications such as still cameras which require high resolution, etc. 20 pin DIP (Ceramic) Features * Progressive scan allows individual readout of the image signals from all pixels. * High horizontal and vertical resolution (both approximately 1024 TV-lines) still images without a mechanical shutter * Supports high frame rate readout mode (effective 256 lines output, 60 frame/s) * Square pixel * Aspect ratio: 4:3 Pin 1 * Horizontal drive frequency: 28.64 MHz 2 * High sensitivity, low smear * Low dark current, excellent anti-blooming characteristics * Continuous variable-speed shutter V * Horizontal register: 5.0 V drive Device Structure 2 * Interline CCD image sensor 40 H Pin 11 * Image size: Diagonal 11 mm (Type 2/3) * Total number of pixels: 1434 (H) x 1050 (V) approx. 1.50M pixels Optical black position * Number of effective pixels: 1392 (H) x 1040 (V) approx. 1.45M pixels (Top View) * Number of active pixels: 1360 (H) x 1024 (V) approx. 1.40M pixels * Chip size: 10.2 mm (H) x 8.3 mm (V) * Unit cell size: 6.45 m (H) x 6.45 m (V) * Optical black: Horizontal (H) direction: Front 2 pixels, rear 40 pixels Vertical (V) direction: Front 8 pixels, rear 2 pixels * Number of dummy bits: Horizontal 20 Vertical 3 * Substrate material: Silicon 8 * EXview HAD CCD is a trademark of Sony Corporation.

Output starts from line 1 in high frame rate readout mode. 1. Progressive scan mode In this mode, all pixel signals are output in non-interlace format in 1/15 s. All pixel signals within the same exposure period are read out simultaneously, making this mode suitable for high resolution image capturing. 2. High frame rate readout mode All effective areas are scanned in approximately 1/60 s by reading out two out of eight lines (1st and 4th lines, 9th and 12th lines, and so on). The vertical resolution is approximately 256 TV-lines. This readout mode emphasizes processing speed over vertical resolution. - 10 - ICX285AL * Measurement conditions (1) In the following measurements, the substrate voltage is set to the value indicated on the device, and the device drive conditions are at the typical values of the progressive scan mode, bias and clock voltage conditions. (2) In the following measurements, spot blemishes are excluded and, unless otherwise specified, the optical black level (OB) is used as the reference for the signal output, which is taken as the value measured at point [*B] of the measurement system. * Definition of standard imaging conditions (1) Standard imaging condition I: Use a pattern box (luminance: 706 cd/m2, color temperature of 3200K halogen source) as a subject. (Pattern for evaluation is not applicable.) Use a testing standard lens with CM500S (t = 1.0 mm) as an IR cut filter and image at F8. The luminous intensity to the sensor receiving surface at this point is defined as the standard sensitivity testing luminous intensity. (2) Standard imaging condition II: This indicates the standard imaging condition I with the IR cut filter removed. (3) Standard imaging condition III: Image a light source (color temperature of 3200K) with a uniformity of brightness within 2% at all angles. Use a testing standard lens with CM500S (t = 1.0 mm) as an IR cut filter. The luminous intensity is adjusted to the value indicated in each testing item by the lens diaphragm. 1. Sensitivity 1 Set to standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of 1/100 s, measure the signal output (VS1) at the center of the screen, and substitute the value into the following formula. S1 = VS1 x 100 [mV] 30 2. Sensitivity 2 Set to standard imaging condition II. After selecting the electronic shutter mode with a shutter speed of 1/500 s, measure the signal output (VS2) at the center of the screen, and substitute the value into the following formula. S2 = VS2 x 500 [mV] 30 3. Saturation signal Set to standard imaging condition III. After adjusting the luminous intensity to 20 times the intensity with the average value of the signal output, 200 mV, measure the minimum value of the signal output. 4. Smear Set to standard imaging condition III. With the lens diaphragm at F5.6 to F8, first adjust the luminous intensity to 500 times the intensity with the average value of signal output, 200 mV. Then after the readout clock is stopped and the charge drain is executed by the electronic shutter at the respective H blankings, measure the maximum value (Vsm [mV]) of the signal output and substitute the value into the following formula. Sm = 20 x log Vsm 1 1 x x 200 500 10 [dB] (1/10 V method conversion value) - 11 - ICX285AL 5. Video signal shading Set to standard imaging condition III. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity so that the average value of the signal output is 200 mV. Then measure the maximum (Vmax [mV]) and minimum (Vmin [mV]) values of the signal output and substitute the values into the following formula. SH = (Vmax - Vmin)/200 x 100 [%] 6. Dark signal Measure the average value of the signal output (Vdt [mV]) with the device ambient temperature 60C and the device in the light-obstructed state, using the horizontal idle transfer level as a reference. 7. Dark signal shading After measuring 6, measure the maximum (Vdmax [mV]) and minimum (Vdmin [mV]) values of the dark signal output and substitute the values into the following formula. Vdt = Vdmax - Vdmin [mV] 8. Lag Adjust the signal output generated by strobe light to 200 mV. After setting the strobe light so that it strobes with the following timing, measure the residual signal (Vlag). Substitute the value into the following formula. Lag = (Vlag/200) x 100 [%] VD Light Strobe light timing Signal output 200 mV Output Vlag (lag) - 12 - Drive Circuit 5.0V 15V 100k 0.1 -7V 0.1 1/35V 20 19 0.1 NC NC NC V1 V4 V2A V2B V3 1 XSUB 18 17 16 15 H2 H1 VL CSUB 2 1 2 3 4 5 6 7 8 GND H2 RG VDD 4 5 SUB XV2 14 20 13 12 11 0.1 19 18 6 CXD3400N (TOP VIEW) ICX285 (BOTTOM VIEW) H1 - 13 - 17 3.3/ 16V 0.1 XSG2B 7 16 15 14 13 12 11 XSG2A 8 XV3 9 XV1 10 VOUT GND XV4 3 9 10 3.3/20V 0.1 1M 0.01 XSUB 2SC4250 4.7k 1/20V CCD OUT H2 H1 RG ICX285AL 1040 1 2 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 9 10 1031 1032 1040 1 2 1 2 - 14 - VD V2A HD V2B V4 V3 V1 Drive Timing Chart (Vertical Sync) Progressive Scan Mode CCD OUT 1063 "a" 1068 1 2 3 4 5 6 7 8 9 10 11 12 13 21 1044 1052 1063 1068 1 ICX285AL Drive Timing Chart (Vertical Sync "a" Enlarged) Progressive Scan Mode H1 392 56 1790 1 392 1790 1 56 70 nsec (2 bits) HD 27.9 sec (800 bits) V1 3.5 sec (100 bits) 140 98 V2A - 15 - 126 1 126 V2B 1 126 182 V3 1 1 210 V4 ICX285AL Drive Timing Chart (Horizontal Sync) Progressive Scan Mode 392 412 1790 1 CLK H1 H2 RG SHP SHD 1 84 42 1 1 42 1 1 126 1 210 126 1 105 126 1 105 126 1 84 126 168 210 1 42 168 56 V1 1 1 V2A 1 V2B 1 V3 1 V4 SUB 430 - 16 - ICX285AL 1020 1025 1028 1033 1036 Drive Timing Chart (Vertical Sync) High Frame Rate Readout Mode 1 4 1 4 9 12 17 20 25 1020 1025 1028 1033 1036 1 4 1 4 9 12 17 20 25 1020 1025 1028 1033 1036 1 4 1 4 9 12 17 - 17 - VD V2A HD V1 V2B V4 V3 CCD OUT 260 261 262 263 264 265 266 267 "a" "a" 1 2 3 4 5 6 7 8 9 10 11 12 13 260 261 262 263 264 265 266 267 1 2 3 4 5 6 7 8 9 10 11 12 13 260 261 262 263 264 265 266 267 1 2 3 4 5 6 7 8 ICX285AL Drive Timing Chart (Vertical Sync "a" Enlarged) High Frame Rate Readout Mode H1 392 56 1790 1 392 1790 1 56 HD 70 nsec (2 bits) 27.9 sec (800 bits) 3.5 sec (100 bits) V1 - 18 - 84 10 10 10 10 10 10 10 10 V2A V2B V3 V4 ICX285AL Drive Timing Chart (Horizontal Sync) High Frame Rate Readout Mode 392 412 1790 1 CLK H1 H2 RG SHP SHD 56 - 19 - 1 1 1 1 1 50 1 1 1 1 1 30 50 1 30 1 105 1 1 50 30 1 30 1 50 1 30 1 50 1 50 1 126 1 30 50 30 1 30 1 1 1 30 30 50 30 1 30 1 50 30 30 50 50 1 50 1 V1 1 30 50 1 50 1 50 1 1 30 50 30 30 30 50 1 20 V2A 1 10 1 V2B 1 10 1 V3 1 V4 1 SUB 430 ICX285AL ICX285AL Notes on Handling 1) 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. 2) Soldering a) Make sure the package temperature does not exceed 80C. b) Solder dipping in a mounting furnace causes damage to the glass and other defects. Use a ground 30W soldering iron and solder each pin in less than 2 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. 3) 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 1000 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) 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. 5) Exposure to high temperature or humidity will affect the characteristics. Accordingly avoid storage or usage in such conditions. 6) CCD image sensors are precise optical equipment that should not be subject to too much mechanical shocks. - 20 - Package Outline Unit: mm C 0 to 9 20 pin DIP (800mil) 31.0 0.4 27.0 0.3 11 A D 2-2.50 - 0 + 0.25 20 ~ ~ 2R 3. 0 26.0 5.0 20.2 0.3 B + 0.15 2.00 - 0 (Reference Hole) x2.5 2.00 - 0 (Elongated Hole) 0.25 0.35 1 + 0.15 13.15 10 0.5 26.0 0.25 3.2 0.3 1.0 5.5 0.2 - 21 - 1.
