Sony Semiconductor
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.
