PRNU is measured using 2490 pixels excluding 3 pixels each at both ends, and is defined as follows: PRNU= ΔX/X × 100 (%) X: average output of all pixels, ΔX: difference between X and maximum output or minimum output *12: Signal components of the preceding line data that still remain even after the data is read out in a saturation output state. Image lag increases when the output exceeds the saturation output voltage. 2 CMOS linear image sensor S12443 Appearance inspection standards Parameter Foreign matter on photosensitive area Test criterion 10 μm max.

The shift register starts operation at the rising edge of CLK immediately after ST goes low. The integration time can be changed by changing the ratio of the high and low periods of ST. If the first Trig pulse after ST goes low is counted as the first pulse, the Video signal is acquired at the rising edge of the 50th Trig pulse. 5 CMOS linear image sensor S12443 Operation example This example assumes that the clock pulse frequency is maximized (video data rate is also maximized), the time of one scan is minimized, and the integration time is maximized. Clock pulse frequency = Video data rate = 10 MHz Start pulse cycle = 2548/f(CLK) = 2548/10 MHz = 254.8 μs High period of start pulse = Start pulse cycle - Start pulse’s low period min. = 2548/f(CLK) - 64/f(CLK) = 2548/10 MHz - 64/10 MHz = 248.4 μs Integration time is equal to the high period of start pulse + 34 cycles of clock pulses, so it will be 248.4 + 3.4 = 251.8 μs. thp(ST)=248.4 μs tlp(ST)=6.4 μs ST tpi(ST)=254.8 μs KMPDC0421EC Dimensional outline (unit: mm) Photosensitive area 17.472 × 0.125 22.9 2.7 8.2 ± 0.2 1 ch 2496 ch Direction of scan Photosensitive surface 0.972 ± 0.2*3 [Top view] Silicone resin 1.6 ± 0.3 1.3 ± 0.15*2 Glass epoxy 0.3 ± 0.15*1 [Side view] 20.32 2.54 2.54 5.08 1.27 [Bottom view] Index mark Electrode (14 ×) ϕ0.5 Tolerance unless otherwise noted: ±0.1 *1: Distance from package surface to photosensitive surface *2: Distance from package bottom to photosensitive surface *3: Distance from package side surface to center of photosensitive KMPDA0295EF 6 CMOS linear image sensor S12443 Pin connections Pin no. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Symbol Vdd CLK Vss NC NC Vss Vdd Video EOS NC NC Trig Vcp ST I/O I I I O O O I I Description Supply voltage Clock pulse GND No connection No connection GND Supply voltage Video signal End of scan No connection No connection Trigger pulse Bias voltage for booster circuit*15 Start pulse *15: Voltage of approx. 5.5 V, which was boosted by the chip's internal booster circuit, appears at the terminal.

Precautions (1) Electrostatic countermeasures · This device has a built-in protection circuit as a safeguard against static electrical charges. However, to prevent destroying the device with electrostatic charges, take countermeasures such as grounding yourself, the workbench and tools. · Protect this device from surge voltages which might be caused by peripheral equipment. (2) Package handling · The photosensitive area of this device is sealed and protected by transparent resin. When compared to a glass faceplate, the surface of transparent resin may be less uniform and is more likely to be scratched. Be very careful when handling this device and also when designing the optical systems. · Dust or grime on the light input window might cause nonuniform sensitivity. To remove dust or grime, blow it off with compressed air. (3) Surface protective tape · Protective tape is affixed to the surface of this product to protect the photosensitive area. After assembling the product, remove the tape before use. 9 CMOS linear image sensor S12443 Related information www.hamamatsu.com/sp/ssd/doc_en.html Precautions ∙ ∙ ∙ ∙ Disclaimer Image sensor Surface mount type products Resin-sealed CMOS linear image sensors Information described in this material is current as of June, 2016.
