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 doublespeed 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

Applications

LCD projectors, etc.
