TCD1709D
TOSHIBA CCD Linear Image Sensor CCD (Charge Coupled Device)
TCD1709D
The TCD1709D is a high sensitive and low dark current 7500
pixels CCD image sensor.
The sensor is designed for facsimile, imagescanner and OCR.
The device contains a row of 7500 pixels photodiodes which
provide a 24 lines/mm (600DPI) across a A3 size paper. The
device is operated by 5-V (pulse), and 12-V power supply.
Features
· Number of image sensing pixels: 7500 pixels
· Image sensing pixel size: 7 µm by 7 µm on 7-µm center
· Photo Sensing Region
: High sensitive and low voltage dark signal pn photodiode
· Clock: CMOS 5-V drive
· Power supply voltage: 12-V power supply
· Package: 68-pin CERDIP

Note 5: VDRK is defined as average dark signal voltage of all effective pixels.
DSNU is defined by the difference between average value (VDRK) and the maximum value of the dark
voltage.

Note 6: Definition of DR : DR = VSAT
VDRK
VDRK is proportional to tINT (integration time).
So the shorter tINT condition makes wider DR values.
Note 7: DC signal output voltage is defined as follows:

Note 8: PRNU (3) is defined as maximum voltage with next pixel, where measured 5% of SE (typ.)
Note 9:
DC differential error voltage is defined as follows:
Definition of DC differential error voltage = |VOSX − VOSY|
VOSX : Maximum DC signal output voltage
VOSY : Minimum DC signal output voltage

Caution
1. Electrostatic Breakdown
Store in shorting clip or in conductive foam to avoid electrostatic breakdown.
CCD Image Sensor is protected against static electricity, but interior puncture mode device due to static
electricity is sometimes detected. In handing the device, it is necessary to execute the following static
electricity preventive measures, in order to prevent the trouble rate increase of the manufacturing system
due to static electricity.
a. Prevent the generation of static electricity due to friction by making the work with bare hands or by
putting on cotton gloves and non-charging working clothes.
b. Discharge the static electricity by providing earth plate or earth wire on the floor, door or stand of the
work room.
c. Ground the tools such as soldering iron, radio cutting pliers of or pincer.
It is not necessarily required to execute all precaution items for static electricity.
It is all right to mitigate the precautions by confirming that the trouble rate within the prescribed
range.
2. Window Glass
The dust and stain on the glass window of the package degrade optical performance of CCD sensor.
Keep the glass window clean by saturating a cotton swab in alcohol and lightly wiping the surface, and
allow the glass to dry, by blowing with filtered dry N2. Care should be taken to avoid mechanical or
thermal shock because the glass window is easily to damage.
3. Incident Light
CCD sensor is sensitive to infrared light. Note that infrared light component degrades resolution and
PRNU of CCD sensor.
4. Soldering
Soldering by the solder flow method cannot be guaranteed because this method may have deleterious
effects on prevention of window glass soiling and heat resistance.
Using a soldering iron, complete soldering within ten seconds for lead temperatures of up to 260°C, or
within three seconds for lead temperatures of up to 350°C.
