Description

The ICX228AL is an interline CCD solid-state

image sensor suitable for EIA B/W video cameras.

Compared with the current product ICX208AL, smear

charactristics are improved drastically and power

consumption is reduced. High sensitivity and high

saturation signal are achieved by Super HAD CCD

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).
