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.

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

Applications

LCD projectors, etc.
