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 CCDTM 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.

1 VL setting is the VVL voltage of the vertical transfer clock waveform, or the same power supply as the VL
power supply for the V driver should be used. (When CXD1267AN is used.)
2 Do not apply a DC bias to the substrate clock pin, because a DC bias is generated within the CCD.

3 VL setting is the VVL voltage of the vertical transfer clock waveform, or the same power supply as the VL
power supply for the V driver should be used. (When CXD1267AN is used.)
4 Connect to GND or leave open.
5 The setting value of the substrate voltage (VSUB) is indicated on the back of the image sensor by a special
code. When adjusting the substrate voltage externally, adjust the substrate voltage to the indicated voltage.
The adjustment precision is ±3%. However, this setting value has not significance when used in substrate
bias internal generation mode.
