CXD3172AR

Signal Processor LSI for Single CCD Color Camera

Description

The CXD3172AR is a signal processor LSI for Ye,

Cy, Mg and G single CCD color cameras. In addition

to basic camera signal processing functions, it

includes an AE/AWB detection circuit, a sync signal

generation circuit and an external sync circuit, etc.

This chip also has a built-in microcontroller to realize

basic camera functions such as AE/AWB without an

external microcomputer.

100 pin LQFP (Plastic)
