Ai325CA
1/3 inch CCD Image Sensor for NTSC Camera
GENERAL DESCRIPTION
The Ai325CA is a 250K pixels CCD area
sensor for NTSC 1/3 inch video cameras.
Buried photodiodes and micro lenses are
adopted for low noise, low smear and high
sensitivity. A chrominance signal is achieved by
the adoption of Yellow, Magenta, Cyan and
Green complementary color mosaic filters. This
product also has the features of strong anti-
blooming and electronic shutter with variable
charge-storage time.
