CXD2464R

Timing Generator for LCD Panels

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

Description

The CXD2464R is a timing signal generator for

driving the LCX026, LCX016 and LCX012BL LCD

panels. This chip has a built-in serial interface circuit

which supports various XGA, SVGA and VGA signals,

and (double speed) NTSC and PAL signals through

external control from a microcomputer, etc.

64 pin LQFP (Plastic)

Features

• Generates the LCX026/LCX016/LCX012BL drive

pulse.

• Supports various SVGA (horizontal scanning frequency:

35 to 54kHz, vertical scanning frequency: 56 to 86Hz)

and VGA (horizontal scanning frequency: 31 to 38kHz,

vertical scanning frequency: 59 to 75Hz) signals.

• Supports simple (skip scan) display of XGA signals

(1024 × 768 dots, horizontal scanning frequency:

57kHz, vertical scanning frequency: 71Hz or less,

clock frequency: 62.5MHz or less).

• Supports simple (skip scan) display of SVGA

signals (800 × 600 dots).

• Supports Macintosh16 signals (LCX016)

• Supports PC-98 signals (640 × 400 dots, horizontal

scanning frequency: 24 to 38kHz, vertical scanning

frequency: 56 to 86Hz).

• Supports NTSC and PAL signals

• Line double-speed display realized with a built-in

double-speed controller (clock frequency: 33.3MHz

or less)

(Line memory µPD485505: NEC)

• Allows control of sample-and-hold position of

CXA2112R sample-and-hold driver.

• Supports up/down inversion and/or right/left inversion.

• Supports line inversion and field inversion

• AC drive of LCD panels during no signal

Note) Supported signals vary according to LCD panel.

Applications

LCD projectors, etc.
