KAI-04070 2048 (H) x 2048 (V) Interline CCD Image Sensor Description The KAI−04070 Image Sensor is a 4-megapixel CCD in a 4/3 inch optical format. Based on the TRUESENSE 7.4 micron Interline Transfer CCD Platform, the sensor provides very high smear rejection and up to 82 dB linear dynamic range through the use of a unique dual-gain amplifier. A flexible readout architecture enables use of 1, 2, or 4 outputs for full resolution readout up to 28 frames per second, while a vertical overflow drain structure suppresses image blooming and enables electronic shuttering for precise exposure control. www.onsemi.com Table 1.

Block Diagram Dark Reference Pixels Image Acquisition There are 16 dark reference rows at the top and 16 dark rows at the bottom of the image sensor. The 24 dark columns on the left or right side of the image sensor should be used as a dark reference. Under normal circumstances use only the center 22 columns of the 24 column dark reference due to potential light leakage. An electronic representation of an image is formed when incident photons falling on the sensor plane create electron-hole pairs within the individual silicon photodiodes. These photoelectrons are collected locally by the formation of potential wells at each photosite. Below photodiode saturation, the number of photoelectrons collected at each pixel is linearly dependent upon light level and exposure time and non-linearly dependent on wavelength. When the photodiodes charge capacity is reached, excess electrons are discharged into the substrate to prevent blooming. Dummy Pixels Within each horizontal shift register there are 12 leading additional shift phases. These pixels are designated as dummy pixels and should not be used to determine a dark reference level. In addition, there is one dummy row of pixels at the top and bottom of the image. ESD Protection Adherence to the power-up and power-down sequence is critical. Failure to follow the proper power-up and power-down sequences may cause damage to the sensor. See Power-Up and Power-Down Sequence section. Active Buffer Pixels 16 unshielded pixels adjacent to any leading or trailing dark reference regions are classified as active buffer pixels. These pixels are light sensitive but are not tested for defects and non-uniformities. www.onsemi.com 3 KAI−04070 Bayer Color Filter Pattern RDcd R2cd R1d VDDd VOUTd H2Bd H2Sd H1Bd H1Sd SUB GND OGc H2SLc H2Bc H2Sc H1Bc H1Sc RDcd R2cd R1c VDDc VOUTc ÑÑÑÑÑÑÑÑÑÑÑÑÑÑÑ ÌÌÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌÌÌ HLOD 1 11 24 16 1024 1024 16 8 24 11 1 1Dummy 16 16 B G G R V1T V2T V3T V4T B G G R GND OGd H2SLd V1T V2T V3T V4T DevID ESD V1B V2B V3B V4B RDab R2ab R1a VDDa VOUTa 2048 (H) × 2048 (V) 7.4 mm × 7.4 mm Pixels 24 16 16 24 B G G R ESD B G G R ÌÌÌÌÌÌÌÌÌÌÌÌÌÌ ÌÌÌÌÌÌÌÌÌÌÌÌÌÌ ÑÑÑÑÑÑÑÑÑÑÑÑÑÑ V1B V2B V3B V4B RDab R2ab R1b VDDb VOUTb 16 Buffer 16 Dark 1 Dummy (Last VCCD Phase = V1 → H1S) 1 11 24 16 8 1024 1024 16 8 24 11 1 HLOD GND OGb H2SLb H2Bb H2Sb H1Bb H1Sb SUB H2Ba H2Sa H1Ba H1Sa GND OGa H2SLa Figure 3.

For each region of interest, a pixel is marked defective if it is greater than or equal to the median value of that region of interest plus the bright threshold specified or if it is less than or equal to the median value of that region of interest minus the dark threshold specified. • Example for major bright field defective pixels: • Average value of all active pixels is found to be 924 mV • Dark defect threshold: 924 mV ⋅ 12% = 111 mV • Bright defect threshold: 924 mV ⋅ 12% = 111 mV • Region of interest #1 selected. This region of interest is pixels 17, 17 to pixels 144, 144 ♦ Median of this region of interest is found to be 920 mV ♦ Any pixel in this region of interest that is ≤ (920 − 111 mV) 809 mV in intensity will be marked defective ♦ Any pixel in this region of interest that is ≥ (920 + 111 mV) 1,031 mV in intensity will be marked defective • All remaining 144 sub regions of interest are analyzed for defective pixels in the same manner Signal of ROI[i] + (ROI Average in Counts * * Horizontal Overclock Average in Counts) @ @ mV per Count Where i = 1 to 256.

If the level or the condition is exceeded, the device will be degraded and may be damaged. Operation at these values will reduce MTTF. Absolute maximum rating is defined as a level or condition that should not be exceeded at any time per the Table 11. ABSOLUTE MAXIMUM RATINGS Description Symbol Minimum Maximum Unit Notes Operating Temperature TOP −50 70 °C 1 Humidity RH 5 90 % 2 Output Bias Current IOUT − 60 mA 3 CL − 10 pF Off-Chip Load Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. Noise performance will degrade at higher temperatures. 2. T = 25°C. Excessive humidity will degrade MTTF. 3. Total for all outputs. Maximum current is −15 mA for each output. Avoid shorting output pins to ground or any low impedance source during operation. Amplifier bandwidth increases at higher current and lower load capacitance at the expense of reduced gain (sensitivity). Table 12.

The HCCD clocks can be run during the electronic shutter pulse as long as the HCCD does not contain valid image data. For short exposures less than one line time, the electronic shutter pulse can appear inside the frame timing. Any electronic shutter pulse transition should be tV/2 away from any VCCD clock transition. Electronic Shutter Timing Diagrams The electronic shutter pulse can be inserted at the end of any line of the HCCD timing. The HCCD should be empty when the electronic shutter is pulsed. A recommended position for the electronic shutter is just after the last pixel is read out of a line.

Pixel Timing Diagram − 1/4 Resolution − Low Gain www.onsemi.com 42 KAI−04070 XLDR Pixel Timing To operate the sensor in extended linear dynamic range (XLDR) mode, the following pixel timing should be used. This mode requires two sets of analog front end (AFE) signal processing electronic units for each output. As shown in Figure 44 one AFE samples the pixel at low gain (SHPLG and SHDLG) and the other AFE samples the pixel at high gain (SHPHG and SHDHG). Two HCCD pixels are summed on the output amplifier node to obtain enough charge to fully use the 82 dB range of the XLDR timing. Combined with two-line VCCD summing, a total of 160,000 electrons of signal (4 × 40,000) SHDLG SHPLG can be sampled with 12 electrons or less noise. Note that a linear dynamic range of 82 dB is very large. Ensure that the camera optics is capable of focusing an 82 dB dynamic range image on the sensor. Lens flare caused by inexpensive optics or even dust on the lens will limit the dynamic range. The timing shown in Figure 46 shows the HCCD not being clocked at a constant frequency. If the HCCD cannot be clocked at a variable frequency, then the HCCD may be clocked at a constant frequency (Figure 45) at the expense of about 33% slower frame rate. Low Gain AFE Low Gain Digital Out High Gain AFE High Gain Digital Out SHPHG Caution: In the XLDR mode the output of the CCD can produce large signals that may damage some AFE devices. If there is the potential for damage to the AFE, the CCD output should be electronically attenuated. SHDHG Sensor Output Figure 44.
