Driver/Timing Generator for Color LCD Panels
Description
The CXA3572R is an IC designed to drive the color
LCD panel ACX306/312.
This IC greatly reduces the number of peripheral
circuits and parts by incorporating a RGB driver and
timing generator for video signals and a VCO 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.
