| ICX085AK Diagonal 11mm (Type 2/3) Progressive Scan CCD Image Sensor with Square Pixel for Color Cameras Description The ICX085AK is a diagonal 11mm (Type 2/3) interline CCD solid-state image sensor with a square pixel array. Progressive scan allows all pixels signals to be output independently within approximately 1/12 second. This chip features an electronic shutter with variable charge-storage time which makes it possible to realize full-frame still image without a mechanical shutter. High resolution and high color reproductivity are achieved through the use of R, G, B primary color mosaic filters. Further, high sensitivity and low dark current are achieved through the adoption of HAD (HoleAccumulation Diode) sensors. This chip is suitable for image input applications such as still cameras which require high resolution. 20 pin DIP (Ceramic) Pin 1 1 Features V * Progressive scan allows individual readout of the image signals from all pixels. * High vertical resolution (1024TV-lines) still image 4 without a mechanical shutter. 56 H * Square pixel unit cell Pin 11 * Aspect ratio 5:4 * Horizontal drive frequency: 20.25MHz Optical black position * Reset gate bias is not adjusted. * Substrate voltage: 5.5 to 12.5V (Top View) * R, G, B primary color mosaic filters on chip * Continuous variable-speed shutter * High resolution, high color reproductivity, high sensitivity, low dark current * Low smear * Excellent antiblooming characteristics * Horizontal register: 5V drive Device Structure * Interline CCD image sensor * Image size: Diagonal 11mm (Type 2/3) * Number of effective pixels: 1300 (H) x 1030 (V) approx. 1.3M pixels * Total number of pixels: 1360 (H) x 1034 (V) approx. 1.4M pixels * Chip size: 10.0mm (H) x 8.7mm (V) * Unit cell size: 6.7m (H) x 6.7m (V) * Optical black: Horizontal (H) direction: Front 4 pixels, rear 56 pixels Vertical (V) direction: Front 3 pixels, rear 1 pixel * Number of dummy bits: Horizontal 24 Vertical 1 * Substrate material: Silicon 3 Wfine CCD is a registered trademark of Sony Corporation.

(Pattern for evaluation is not applicable.) Use a testing standard lens with CM500S (t = 1.0mm) as an IR cut filter and image at F5.6. 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 : 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 = 1.0mm) as an IR cut filter. The luminous intensity is adjusted to the value indicated in each testing item by the lens diaphragm. 1. G sensitivity, sensitivity comparison Set to standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of 1/80s, measure the signal outputs (VGr, VGb, VR and VB) at the center of each Gr, Gb, R and B channel screens, and substitute the values into the following formula. VG = (VGr + VGb)/2 Sg = VG x 80 [mV] 12 Rr = VR/VG Rb = VB/VG 2. Saturation signal Set to standard imaging condition II. After adjusting the luminous intensity to 10 times the intensity with the average value of the Gr signal output, 150mV, measure the minimum values of the Gr, Gb, R and B signal outputs. 3. Smear Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, first adjust the average value of the Gr signal output to 150mV. Measure the average values of the Gr signal output, Gb signal output, R signal output and B signal output (Gra, Gba, Ra and Ba), and then adjust the luminous intensity to 500 times the intensity with average value of the Gr signal output, 150mV. 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]), independent of the Gr, Gb, R and B signal outputs, and substitute the values into the following formula. Sm = VSm / Gra + Gba + Ra + Ba 1 x x 1 x 100 [%] (1/10V method conversion value) 4 500 10 4. Video signal shading Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity so that the average value of the Gr signal output is 150mV. Then measure the maximum (Grmax [mV]) and minimum (Grmin [mV]) values of the Gr signal output and substitute the values into the following formula. SHg = (Grmax - Grmin)/150 x 100 [%] - 11 - ICX085AK 5. Uniformity between video signal channels After measuring 4, measure the maximum (Rmax [mV]) and minimum (Rmin [mV]) values of the R signal and the maximum (Bmax [mV]) and minimum (Bmin [mV]) values of the B signal, and substitute the values into the following formula. Srg = (Rmax - Rmin)/150 x 100 [%] Sbg = (Bmax - Bmin)/150 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. Line crawl Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the Gr signal output is 150mV, and then insert R, G, and B filters and measure the difference between G signal lines (Glr, Glg, Glb [mV]) as well as the average value of the G signal output (Gar, Gag, Gab). Substitute the values into the following formula. Lci = Gli x 100 [%] (i = r, g, b) Gai 9. Lag Adjust the Gr signal output value generated by strobe light to 150mV. 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/150) x 100 [%] FLD SG Light Strobe light timing Gr signal output 150mV Output Vlag (Lag) - 12 - Drive Circuit 15V 100k 0.1 -7.5V 22/16V 5V 22/20V 2SK523 1/10V 2.7k 47 CXD1268M x2 0.1 22/10V XV2 XSG 1 2 N.C. 3 4 N.C. 5 6 7 N.C. 8 9 20 19 18 17 N.C. 16 15 14 N.C. 13 12 11 10 CCD OUT XV1 XV3 1 2 3 4 5 6 7 8 9 10 22/16V 20 19 18 17 16 15 14 13 12 11 1M 3.3/20V 100k 3.3/16V 0.01 22/20V N.C. 1 2 3 4 5 6 7 N.C. 8 9 N.C. 10 20 N.C. 19 N.C. 18 17 16 15 N.C. 14 N.C. 13 12 N.C. 11 AC04 AC04 XH2 0.01 ICX085AK XH1 RG H2 H1 GND RG NC NC SUB GND VDD VRD 1/20V - 13 - 1/35V VSUB XSUB CXD1267AN V3 V2 V1 VL GND GND NC CGG GND VOUT ICX085 (BOTTOM VIEW) ICX085AK Spectral Sensitivity Characteristics (Includes lens characteristics, excludes light source characteristics) 1 0.9 R 0.8 B 0.7 G Relative Response 0.6 0.5 0.4 0.3 0.2 0.1 0 400 500 Wave Length [nm] 600 700 - 14 - Sensor Readout Clock Timing Chart HD 4.0s (81 bits) 5.0s (102 bits) 33.7s (683 bits) SG - 15 - V1 V2 V3 ICX085AK Drive Timing Chart (Vertical Sync) VD HD 5 10 15 SG V1 V2 V3 1030 1031 12345 CCD OUT 1044 1 20 - 16 - ICX085AK Drive Timing Chart (Horizontal Sync) HD CLK 297 321 326 H1 232 1 24 1 1616 1 H2 RG SHP - 17 - 57 1 19 1 1 1 38 1 1 167 42 1 57 57 SHD 65 1 65 1 V1 175 156 1 V2 V3 1 137 SUB 1 23 19 CCD OUT OPB (4 bits) OPB (56 bits) ICX085AK ICX085AK 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) Operate in clean environments (around class 1000 is appropriate). 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, color filters will be discolored. When high luminance objects are imaged with the exposure level control by electronic-iris, the luminance of the imageplane may become excessive and discolor of the color filter will possibly be accelerated. In such a case, it is advisable that taking-lens with the automatic-iris and closing of the shutter during the power-off mode should be properly arranged. 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. - 18 - Package Outline Unit: mm 20pin DIP (800mil) 0 to 9 11 A D C 31.0 0.4 27.0 0.3 + 0.25 2-2.50 0 20 ~ ~ 2R3 .0 26.0 5.0 B + 0.15 2.00 0 (Reference Hole) 0.35 3.2 0.3 1.0 0.3 M 5.5 0.2 - 19 - 0.46 1.27 1.
