CXA3268AR
Driver/Timing Generator for Color LCD Panels
Description
The CXA3268AR is an IC designed to drive the color
LCD panels ACX300, ACX301, ACX302 and ACX703.
This IC greatly reduces the number of peripheral
circuits and parts by incorporating a RGB driver and
timing generator for video signals onto a single chip.
This chip has a built-in serial interface circuit and
electronic attenuators which allow various settings to
be performed by microcomputer control, etc.
