ICX278AK
Diagonal 4.5mm (Type 1/4) CCD Image Sensor for NTSC Color Video Cameras
Description
The ICX278AK is an interline CCD solid-state
image sensor suitable for NTSC color video cameras
with a diagonal 4.5mm (Type 1/4) system. Compared
with the current product ICX208AK, basic
characteristics such as sensitivity, smear and
dynamic range are improved drastically through the
adoption of EXview HAD CCDTM technology.
This chip features a field period readout system and
an electronic shutter with variable charge-storage time.
The package is a 10mm-square 14-pin DIP (Plastic).
EXview HAD CCDTM has different spectral
characteristics from the current CCD.
14 pin DIP (Plastic)
Features
• High sensitivity (+5dB compared with the ICX208AK)
• Low smear (–20dB compared with the ICX208AK)
• High D range (+2dB compared with the ICX208AK)
• Horizontal register: 3.3 to 5.0V drive
• Reset gate:
3.3 to 5.0V drive
• No voltage adjustment
(Reset gate and substrate bias are not adjusted.)
• High resolution, low smear and low dark current
• Excellent antiblooming characteristics
• Continuous variable-speed shutter
• Recommended range of exit pupil distance: –20 to –100mm
• Ye, Cy, Mg, and G complementary color mosaic filters on chip
