Sony ILX514 Datasheet
3918-pixel CCD Linear Image Sensor (B/W)
For the availability of this product, please contact the sales office.
Description
The ILX514 is a reduction type CCD linear sensor
developed for high resolution facsimiles and copiers.
This sensor reads A4-size documents at a density of
400 DPI (Dot Per Inch). A built-in timing generator
and clock-drivers ensure direct drive at 5V logic for
easy use. In addition, reset pulse can be switched
between internal generation and external input.
Features
• Number of effective pixels: 3918 pixels
• Pixel size: 7µm × 7µm (7µm pitch)
• Built-in timing generator and clock-drivers
• Ultra low lag/ultra high sensitivity/low dark output
• Single output method
• Maximum clock frequency: 5MHz

Notes)
1) In accordance with the given electrooptical characteristics, the even black level is defined as the mean
value of D8, D10, D12 and D14.
The odd black level is defined as the mean value of D7 , D9, D11 and D13.
2) For the sensitivity test light is applied with a uniform intensity of illumination.
3) W lamp (2854K)
4) PRNU is defined as indicated below. Ray incidence conditions are the same as for Note 2.
PRNU = × 100 [%]
(VMAX – VMIN)/2
VAVE
Where the 3918 pixels are divided into blocks of 98, even and odd pixels, respectively (Even and odd last
blocks are 97). The maximum output of each block is set to VMAX, the minimum output to VMIN and the
average output to VAVE.
5) Use below the minimum value of the saturation output voltage.
6) Saturation exposure is defined as follows.
SE =
VSAT
R1
7) Indicates the DC difference in value between odd black level and even black level.
8) Optical signal accumulated time τ int stands at 10ms.
