PAS6311LT CMOS VGA DIGITAL IMAGE SESNSOR

General Description

The PAS6311LT is a highly integrated CMOS active-pixel image sensor that has a VGA resolution of

PAS6311LT outputs 10-bit RGB raw data through a parallel data bus. It is available in 24-pin CSP.

The PAS6311LT can be programmed to set the exposure time for different luminance condition via I2C

TM

serial control bus. By programming the internal register set, it performs on-chip frame rate adjustment, offset

correction DAC and programmable gain control.
