| ICX422AL Diagonal 11mm (Type 2/3) CCD Image Sensor for EIA B/W Video Cameras Description The ICX422AL is an interline CCD solid-state image sensor suitable for EIA B/W video cameras with a diagonal 11mm (Type 2/3) system. Compared with the current product ICX082AL, basic characteristics such as sensitivity and smear are improved drastically and high saturation characteristics are realized. This chip features a field period readout system and an electronic shutter with variable charge-storage time. This chip is compatible with the pins of the ICX082AL and has the same drive conditions. Features * High sensitivity (+3.0dB compared with the ICX082AL) * Low smear (-10.0dB compared with the ICX082AL) * High saturation signal (+2.0dB compared with the ICX082AL) * High resolution and Low dark current * Excellent antiblooming characteristics * Continuous variable-speed shutter 20 pin DIP (Ceramic) Pin 1 2 V 12 3 Pin 11 H 40 Optical black position Device Structure (Top View) * Interline CCD image sensor * Optical size: Diagonal 11mm (Type 2/3) * Number of effective pixels: 768 (H) x 494 (V) approx. 380K pixels * Total number of pixels: 811 (H) x 508 (V) approx. 410K pixels * Chip size: 10.25mm (H) x 8.5mm (V) * Unit cell size: 11.6m (H) x 13.5m (V) * Optical black: Horizontal (H) direction: Front 3 pixels, rear 40 pixels Vertical (V) direction: Front 12 pixels, rear 2 pixels * Number of dummy bits: Horizontal 22 Vertical 1 (even fields only) * Substrate material: Silicon Sony reserves the right to change products and specifications without prior notice.

Definition of standard imaging conditions 1) Standard imaging condition I: Use a pattern box (luminance 706cd/m2, color temperature of 3200K halogen source) as a subject. (Pattern for evaluation is not applicable.) Use a testing standard lens with CM500S (t = 1.00mm) 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 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 = 1.00mm) as an IR cut filter. The luminous intensity is adjusted to the value indicated in each testing item by the lens diaphragm. 1. Sensitivity Set to standard imaging condition I. After selecting the electronic shutter mode with a shutter speed of 1/250s, measure the signal output (Vs) at the center of the screen and substitute the value into the following formula. S = Vs x 250 60 [mV] 2. Saturation signal Set to standard imaging condition II. After adjusting the luminous intensity to 10 times the intensity with average value of signal output, 350mV, measure the minimum value of the signal output. -9- ICX422AL 3. Smear Set to standard imaging condition II. With the lens diaphragm at F5.6 to F8, adjust the luminous intensity to 500 times the intensity with average value of the signal output, 350mV. When 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 x 1 x 1 500 10 350 x 100 [dB] (1/10V method conversion value) 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 signal output is 350mV. 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)/350 x 100 [%] 5. 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. 6. Dark signal shading After measuring 5, 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] 7. Flicker Set to standard imaging condition II. Adjust the luminous intensity so that the average value of the signal output is 350mV, and then measure the difference in the signal level between fields (Vf [mV]). Then substitute the value into the following formula. F = (Vf/350) x 100 [%] 8. Lag Adjust the signal output value generated by strobe light to 350mV. 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/350) x 100 [%] FLD V1 Light Strobe light timing Signal output 350mV Output Vlag (lag) - 10 - Drive Circuit 30V 15V 10k 56k 270k 0.01 15 27k 22/20V 0.01 22k 0.1 3.3/ 16V 39k 1000P 33k 15 47k 15k 3.3/35V 15k 3.3/35V XSUB -9V 5V XV1 XSG1 XV2 7 6 5 4 3 2 1 2200P CXD1268M 1M 17 18 19 20 10 9 8 VL V2 V4 V3 V1 NC SUB XV3 ICX422AL (BOTTOM VIEW) 91k 1/16V 100k 10 10 3.3/16V 100 0.1 10k [A] CCD OUT 47k 0.1 100k 10/10V 3.3k 39k 33k 100k HIS H2 H1 VL RG RD GND VSS VGG VOUT -11V 20 19 18 17 16 GND 15 14 750 100k 13 12 GND 11 3.3/ 16V 3.3/16V H2 0.1 0.1 H1 RG 6V 74AC04 2.2/16V 0.1 VDD - 11 - 14 15 16 3.3/25V 1 11 12 13 3.3/25V 0.01 2 3 4 5 6 7 8 9 10 XV4 XSG2 ICX422AL ICX422AL Spectral Sensitivity Characteristics (includes lens characteristics, excludes light source characteristics) 1.0 0.9 0.8 0.7 Relative Response 0.6 0.5 0.4 0.3 0.2 0.1 0 400 500 600 700 Wave Length [nm] 800 900 1000 Sensor Readout Clock Timing Chart V1 V2 Odd Field V3 V4 33.5 1.6 0.2 2.5 2.5 2.5 2.5 V1 V2 Even Field V3 V4 Unit: s - 12 - Drive Timing Chart (Vertical Sync) FLD VD BLK HD 10 15 20 520 525 1 2 3 4 5 V1 V2 V3 V4 246 135 246 135 135 246 494 493 CCD OUT 493 494 260 265 270 275 135 246 280 - 13 - ICX422AL Drive Timing Chart (Horizontal Sync) HD BLK H1 1 2 3 5 10 10 30 40 20 22 1 2 3 1 2 3 20 H2 760 - 14 - RG V1 V2 V3 V4 SUB 768 1 2 3 5 10 20 ICX422AL ICX422AL 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 30W soldering iron with a ground wire 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. 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. - 15 - 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 1Pin Index 1.
