ICX285AL
Diagonal 11 mm (Type 2/3) Progressive Scan CCD Image
Sensor with Square Pixel for B/W Cameras
Description
The ICX285AL is a diagonal 11 mm (Type 2/3)
interline CCD solid-state image sensor with a square
pixel array. High sensitivity and low smear are
achieved through the adoption of EXview HAD CCD
technology. Progressive scan allows all pixel’s signals
to be output independently within approximately
1/15 second. Also, the adoption of high frame rate
readout mode supports 60 frames per second. This
chip features an electronic shutter with variable
charge-storage time which makes it possible to realize
full-frame still images without a mechanical shutter.
This chip is suitable for image input applications
such as still cameras which require high resolution,
etc.
20 pin DIP (Ceramic)
Features
Progressive scan allows individual readout of the image signals from all pixels.
High horizontal and vertical resolution (both approximately 1024 TV-lines) still images without a mechanical
shutter
Supports high frame rate readout mode (effective 256 lines output, 60 frame/s)

VRGLH is the maximum value and VRGLL is the minimum value of the coupling waveform during the period from
Point A in the above diagram until the rising edge of RG.
In addition, VRGL is the average value of VRGLH and VRGLL.
VRGL = (VRGLH + VRGLL)/2
Assuming VRGH is the minimum value during the interval twh, then:
VφRG = VRGH VRGL
Negative overshoot level during the falling edge of RG is VRGLm.
