Decoder/Driver/Timing Generator for Color LCD Panels
Description
The CXA2503AR is an IC designed exclusively to
drive color LCD panels LCX005BK/BKB and
LCX009AK/AKB.
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 panels LCX005BK/BKB and LCX009AK/
AKB driver
• Supports NTSC and PAL systems
• Supports 16:9 wide display
• Supports composite inputs, Y/C inputs and Y/color
difference inputs

Setting Conditions for Measuring Electrical Characteristics
When measuring the electrical characteristics, the TG (timing generator) block must be initialized by performing
Settings 1 and 2 below.
Setting 1. System reset
After turning on the power, set SW1 to ON and start up V1 from GND in order to activate the TG
block system reset. (See Fig. 1-1.)
Setting 2. Horizontal AFC adjustment
Input SIG5 (VL = 0mV) to (A) and adjust serial bus register PLL ADJ so that WL and WH of the
TP12 output waveform are the same. (See Fig. 1-2.)
