ICX074AK Diagonal 8mm (Type 1/2) Progressive Scan CCD Image Sensor with Square Pixel for Color Video Cameras Description The ICX074AK is a diagonal 8mm (Type 1/2) interline CCD solid-state image sensor with a square pixel array which supports VGA format. Progressive scan allows all pixels signals to be output independently within approximately 1/60 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 and processing applications. 22 pin DIP (Cer-DIP) AAAAA AAAAA AAAAA AAAAA AAAAA Pin 1 V Features • Progressive scan allows individual readout of the 2 image signals from all pixels. 31 H Pin 12 • High vertical resolusion (480TV-lines) still picture without a mechanical shutter.

Gb B Gb B R Gr R Gr Gr and Gb denote the G signals on the same line as the R signal and the B signal, respectively. Gb B Gb B R Gr R Gr Readout modes The output methods for the two readout modes indicated below are now described. 1/60s interlaced 1/30s non-interlaced Gb B R Gr Odd field VOUT1 VOUT2 Gb B R Gr Gb B R Gr VOUT1 VOUT2 Even field VOUT1 VOUT2 1. 1/60s interlaced In this mode, the signals are output in a 1/60s period using the two output pins (VOUT1, VOUT2). The signals from two adjacent horizontal lines are simultaneously output from the respective output pins. The lines output from the output pins are changed over with each field. The VOUT1 signal after it has passed through the CDS and other external circuits or the signal produced by adding the VOUT1 and VOUT2 signals accommodate interlaced scanning. In the Odd field, R signal and Gr signal are output from VOUT1 pin and Gb signal and B signal are output from VOUT2 pin. In the Even field, Gb signal and B signal are output from VOUT1 pin and R signal and Gr signal are output from VOUT2 pin. 2. 1/30s non-interlaced In this mode, the signals are output in a 1/30s period using only one output pin (VOUT1). Unlike the 1/60s interlaced mode described above, the external circuit can be simplified. The imaging characteristics also differ from those of the other modes. R signal and Gr signal lines and Gb signal and B signal lines are output sequentially from VOUT1 pin only. – 12 – ICX074AK Image Sensor Characteristics Measurement Method 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 bias and clock voltage conditions. 2) In the following measurements, spot blemishes are excluded and, unless otherwise specified, the optical black (OB) level is used as the reference for the signal output, which is taken as the value of the Gr/Gb signal output or R/B signal output of signal output 1 in the measurement system. 3) In the following measurements, this image sensor is operated in 1/60s interlaced mode. 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 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 = 1.00mm) 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 1/100s, 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 × 100 [mV] 60 Rr = VR/VG Rb = VB/VG 2. Saturation signal Set to standard imaging condition II. After adjusting the luminous intensity to 20 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 (Sm1 [mV]) of signal output 1 and the maximum value (Sm2 [mV]) of signal output 2, and substitute the values into the following formula. Sm = Sm1 + Sm2 Gra + Gba + Ra + Ba 1 1 ÷ × × × 100 [%] (1/10V method conversion value) 2 4 10 500 – 13 – ICX074AK 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 × 100 [%] 5. Uniformity between video signal channels After measuring 4, measure the maximum (Rmax [mV]) and minimum (Rmin [mV]) values of R signal, and the maximum (Bmax [mV]) and minimum (Bmin [mV]) values of B signal. Substitute the values into the following formula. ∆Srg = (Rmax – Rmin)/150 × 100 [%] ∆Sbg = (Bmax – Bmin)/150 × 100 [%] 6. Dark signal Measure the average value of the signal output 1 (Vdt [mV]) with the device ambient temperature 60°C 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 1 and substitute the values into the following formula. ∆Vdt = Vdmax – Vdmin [mV] 8. 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) × 100 [%] FLD SG Light Strobe light timing Gr signal output 150mV Output – 14 – Vlag (lag) – 15 – RG XHφ1 XHφ2 XSUB XVHOLD XHHG1-1 XHHG1-2 XHHG2-1 XHHG2-2 XVOG XV1 XV3 XV2 XSG 5V –7.5V 22/10V 22 /16V 22/16V 10 8 9 1 2 3 4 5 6 7 CXD1250 CXD1268M 22/10V 12 11 17 16 15 14 13 18 20 19 13 12 11 20 19 18 17 N.C. 16 15 14 22/16V 1/35V 10/20V 22/20V 100k 3.3/16V 1/10V 1/35V 1/35V 1 2 3 4 5 6 7 8 9 10 11 ICX074 (BOTTOM VIEW) 0.01 HC04 HC04 1/20V 100 22 21 20 19 18 17 16 15 14 13 12 HIG2 HIGφ1 HIS VOGφ POGφ 1 2 N.C. 3 4 5 6 7 N.C. 8 9 10 56k HHGφ2 HHGφ1 Hφ2 Hφ1 SUB VL RG 15V Vφ3 Vφ2 Vφ1 VHOLDφ GND CGG1 VOUT1 CGG2 VOUT2 VDD Drive Circuit 3.3/20V 2SK523 1/10V 2SK523 27k 0.1 0.1 0.01 3.9k 100 3.9k 100 0.1 270k 39 2SC2785 × 3 1M 15k 47k 15k [∗B] CCD OUT2 [∗A] CCD OUT1 ICX074AK ICX074AK Spectral Sensitivity Characteristics (Includes lens characteristics, excludes light source characteristics) 1 0.9 R 0.8 B G Relative Response 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 400 500 600 700 Wave Length [nm] Sensor Readout Clock Timing Chart 1/60s interlaced mode HD V1 Odd Field V2 V3 42.5 2.53 2.53 2.94 V1 Even Field V2 V3 Unit : µs – 16 – CCD OUT2 SG CCD OUT1 V3 V2 V1 HD BLK VD FLD 1 3 5 7 1/60s interlaced mode 525 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 1 3 5 7 Drive Timing Chart (Vertical Sync) 494 493 2 4 6 8 2 4 6 8 – 17 – 260 261 262 263 264 265 493 494 270 1 3 5 7 1 3 5 7 2 4 6 8 275 2 4 6 8 280 285 ICX074AK – 18 – SUB SHD SHP RG H2 H1 HHG2 HHG1 VHOLD VOG V3 V2 V1 CLK BLK HD Drive Timing Chart (Horizontal Sync) 1/60s interlaced mode ICX074AK ICX074AK 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 80°C. 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) 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.) AAAA AAAA AAAA AAAA AAAA AAAA AAAA AAAA Upper ceramic Lower ceramic 39N 29N 29N 0.9Nm Low melting point glass Compressive strength Shearing strength Tensile strength Torsional strength 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. – 19 – ICX074AK 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 upper and lower ceramic are joined by low melting point glass. Therefore, care should be taken not to perform the following actions as this may cause cracks. • Applying repeated bending stress to the outer leads. • Heating the outer leads for an extended period with a soldering iron. • Rapidly cooling or heating the package. • Applying any load or impact to a limited portion of the low melting point glass using tweezers or other sharp tools. • Prying at the upper or lower ceramic using the low melting point glass as a fulcrum. Note that the same cautions also apply when removing soldered products from boards. e) 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, color filters will be discolored. When high luminance objects are imaged with the exposure level control by electronic-iris, the luminance of the image-plane 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.
