Timing Generator for LCD Panels

CXD3500R

Description

The CXD3500R is a timing signal generator for

driving the LCD panels of Sony data projectors. This

chip has a built-in serial interface circuit which

supports various SXGA (skip scan display), XGA,

SVGA and VGA signals, and (double speed) NTSC

and PAL signals through external control from a

microcomputer, etc.

Direct drive of LCD panels is possible using 5V

drive.

Features

• Generates the drive pulses for the LCD panels of

Sony high-temperature polycrystalline silicon TFT

data projectors.

• Supports various SXGA, XGA, SVGA and VGA signals.

• Programmable output signals allow the optimal

pulse output settings for each panel.

• Programmable skip scan display allows skip scan

display of various signals (SXGA → XGA, XGA →

SVGA, Macintosh16 → SVGA, etc.)

• Supports NTSC and PAL signals with line double-

speed display using a built-in double-speed

controller. (clock frequency: 36MHz 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
