Timing Generator for LCD Panels
For the availability of this product, please contact the sales office.
Description
The CXD2442Q is a timing signal generator for the
80 pin QFP (Plastic)
SVGA LCD panel LCX016 and VGA LCD panel
LCX012BL driver. This chip has a built-in serial
interface circuit which supports various SVGA and
VGA signals as well as double-speed NTSC and
PAL signals through external control from a
microcomputer, etc.
Features
• Generates the LCX016/LCX012BL drive pulse.
• Supports various SVGA and VGA signals.
(LCX016/LCX012BL)
LCX016
• Aspect conversion performed at the panel side for
the 832 × 624 (Macintosh17), 800 × 600 (SVGA),
640 × 480 (VGA/NTSC), 762 × 572 (PAL),
640 × 400 (PC-98), 832 × 480 (WIDE) modes.
• Line double-speed display realized with a built-in
double-speed controller. (NTSC/PAL) (Line memory
µPD485505: NEC)
LCX012BL
• 640 × 480 (VGA/NTSC/PAL)
• Line double-speed display realized with a built-in
double-speed controller. (NTSC/PAL) (Line memory
µPD485505: NEC)
• Supports double-speed PAL pulse eliminate.
• Supports SVGA pulse eliminate.
• Supports PC-98 (640 × 400) line display.
• Generates timing signal of external sample-and-
hold circuit. (for RGB driver and high voltage drive
sample and hold)
• Supports up/down and/or right/left inversion.
• Supports 1H inversion.
• AC drive of LCD panels during no signal
