Description

The CXD2442Q is a timing signal generator for the 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-andhold 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
