LR38603

Digital Signal Processor for

Color CCD Cameras

DESCRIPTION

The LR38603 is a CMOS digital signal processor for

color CCD video camera systems of 270 k/320 k/

410 k/470 k-pixel CCDs with complementary color

filters. The video camera system consists of

CDS/PGA/ADC IC (IR3Y48A1), DSP IC (LR38603)

and V driver IC (LR36685) with CCD.
