Introduction
Description
The KAI-1020 is a one megapixel interline CCD image sensor with integrated clock drivers and
correlated double sampling. The progressive scan architecture and global electronic shutter provides
excellent image quality for full motion video and still image capture. The integrated clock drivers
allow easy use with CMOS logic timing generators.
Features
1 million pixels, 1000 (H) by 1000 (V)
10 bits dynamic range at 40 MHz
Large 7.4 m square pixels for high sensitivity
Progressive scan (non-interlaced)
Integrated vertical clock drivers
Integrated correlated double sampling (CDS) up to 40 MHz
Integrated electronic shutter driver
Reversible HCCD capable of 40MHz operation
All timing inputs 0 to 5 Volts
Single or dual video output operation
Progressive scan or interlaced
30 Frames per second progressive scan, one output
48 Frames per second progressive scan, two outputs
49 Frames per second interlaced, one output
Fast dump gate for high speed sub-window readout
Antiblooming protection
