CXA2543R
Decoder/Driver/Timing Generator for Color LCD Panels
Description
The CXA2543R is an IC designed exclusively to
drive the color LCD panel DCX501BK and LCX018AK.
This IC greatly reduces the number of circuits and
parts required to drive LCD panels by incorporating
RGB decoder functions for video signals, driver
functions, and a timing generator for driving panels
onto a single chip.
This chip has a built-in serial interface circuit and
electronic attenuators which allow various mode
settings and adjustments to be performed through
direct control from an external microcomputer, etc.
Features
• Color LCD panel DCX501BK and LCX018AK driver
• Supports NTSC and PAL signals
• Supports 16:9 wide display
• Supports composite inputs, Y/C inputs and Y/color
difference inputs
