TCD2560D
TOSHIBA CCD Image Sensor CCD (charge coupled device)
TCD2560D
The TCD2560D is a high sensitive and low dark current 5400
elements × 3 line CCD color image sensor which includes CCD
drive circuit and clamp circuit. The sensor is designed for
scanner.
The device contains a row of 5400 elements × 3 line
photodiodes which provide a 24 lines/mm (600 dpi) across a A4
size paper. The device is operated by 5 V pulse, and 12 V power
supply.

Note 7: VDRK is defined as average dark signal voltage of all effective pixels.
DSNU is defined as different voltage between VDRK and VMDK when VMDK is maximum dark signal
voltage.
Note 8: DC signal output voltage is defined as follows.
Reset Noise Voltage is defined as follows.
Note 9: Random noise is defined as the standard deviation (sigma) of the output level difference between two
adjacent effective pixels under no illumination (i.e. dark conditions) calculated by the following procedure.
1) Two adjacent pixels (pixel n and n + 1) in one reading are fixed as measurement points.
2) Each of the output level at video output periods averaged over 200ns period to get V (n) and V (n + 1).
3) V (n + 1) is subtracted from V (n) to get DV.
DV = V (n) - V (n + 1)
4) The standard deviation of DV is calculated after procedure 2) and 3) are repeated 30 times (30
readings).
