ICX248AL
Diagonal 8mm (Type 1/2) CCD Image Sensor for EIA Black-and-White Video Cameras
Description
The ICX248AL is an interline CCD solid-state
image sensor suitable for EIA black-and-white video
cameras with a diagonal 8mm (Type 1/2) system.
Sensitivity, smear, D-range, S/N and other
characteristics from visible light area to near infrared
light area, have been greatly improved compared
with the ICX038DLA 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 and can replace the
ICX038DLA.
