CXA1854AR

Decoder/Driver/Timing Generator for Color LCD Panels

For the availability of this product, please contact the sales office.

Description

The CXA1854AR is an IC designed exclusively to

64 pin LQFP (Plastic)

drive color LCD panels LCX009AK/AKB/LCX005BK/

BKB. 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.

Features

• Color LCD panels

LCX009AK/AKB/LCX005BK/BKB driver

• Both NTSC/PAL compatible

• Supports composite inputs, Y/C inputs and Y/color

difference inputs

• Band-pass filter, trap and delay line

• Sharpness function

• 2-point γ compensation circuits

• R, B output delay time adjustment circuit

(supports both right and left inversion)

• Polarity reversed circuit / line inverted mode

• Supports external RGB input

• Supports line inversion

• Supports AC drive for LCD panel during no signal

Applications

• Color LCD viewfinders

• Liquid crystal projectors

• Industrial monitors
