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
