Ai3152
Digital Signal Processor for Color CCD Camera
General Description
The Ai3152 is the digital signal-processing chip for color video camera. It includes timing generator
and digital/analog output. Supports 250K / 380K NTSC system CCD sensors and 290K / 440K PAL
system CCD sensors with complementary color filter. It also provided line lock function.
Features
• Support Ye, Cyan, Magenta, Green complementary color filter CCD sensors for
NTSC : Ai325CA(250K), Ai338CA(380K)
PAL : Ai329CA(290K), Ai344CA(440K)
