ICX414AQ
Diagonal 8mm (Type 1/2) Progressive Scan CCD Image Sensor with Square Pixel for Color Cameras
Description
The ICX414AQ is a diagonal 8mm (Type 1/2) interline
CCD solid-state image sensor with a square pixel
array suitable for VGA format. Progressive scan
allows all pixel's signals to be output independently
within approximately 1/60 second. This chip features
an electronic shutter with variable charge-storage
time which makes it possible to realize full-frame still
image without a mechanical shutter. High resolution
and high color reproductivity are achieved through
the use of R, G, B primary color mosaic filters.
Further, high sensitivity and low dark current are
achieved through the adoption of HAD (Hole-
Accumulation Diode) sensors.
This chip is suitable for applications such as FA
and surveillance cameras.
Features
• Progressive scan allows individual readout of the image signals
from all pixels.
• High sensitivity
• Low smear
• High vertical resolution still images without a mechanical shutter
• Square pixel
• Supports VGA format
• Horizontal drive frequency: 24.54MHz
• R, G, B primary color mosaic filters on chip
• No voltage adjustments (reset gate and substrate bias are not
adjusted.)
• High resolution, low dark current, high color reproductivity
• Continuous variable-speed shutter
• Excellent anti-blooming characteristics

∗2 Indications of substrate voltage setting value
Set SUBCIR pin to open when applying a DC bias the substrate clock pin.
Adjust the substrate voltage because the setting value of the substrate voltage is indicated on the back of
image sensor by a special code when applying a DC bias the substrate clock pin.
