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

• Serial interface circuit

• Electronic attenuators (D/A converter)

• BPF, trap and delay line

• Sharpness function

• 2-point γ correction circuit

• R, G, B signal delay time adjustment circuit

• Polarity inversion circuit (line inverted mode)

• Supports external RGB input

• Supports AC drive for LCD panel during no signal

Applications

• Compact LCD monitors

• LCD viewfinders

• Compact liquid crystal projectors, etc.
