ICX428AKL
20 pin DIP (Cer-DIP)
Diagonal 8mm (Type 1/2) CCD Image Sensor for NTSC Color Video Cameras
Description
The ICX428AKL is an interline CCD solid-state
image sensor suitable for NTSC color video cameras
with a diagonal 8mm (Type 1/2) system. Compared
with the current product ICX248AK, basic
characteristics such as sensitivity, smear, dynamic
range and S/N are improved drastically through the
adoption of EXview HAD CCD
TM
technology.
This chip features a field period readout system and
an electronic shutter with variable charge-storage
time. This chip is compatible with the pins of the
ICX248AK and has the same drive conditions.
EXview HAD CCD
TM
has different spectral
characteristics from the current CCD.
Features
High sensitivity (+3dB compared with the ICX248AK)
Low smear (–4dB compared with the ICX248AK)
High D range
High S/N
High resolution and low dark current
Excellent antiblooming characteristics
Ye, Cy, Mg, and G complementary color mosaic filters on chip
Continuous variable-speed shutter
Substrate bias:
Adjustment free (external adjustment also possible with 6 to 14V)
Reset gate pulse:
5Vp-p adjustment free (drive also possible with 0 to 9V)
Horizontal register: 5V drive
