CXD3500R
Timing Generator for LCD Panels
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.
