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
