CXD2464R
Timing Generator for LCD Panels
For the availability of this product, please contact the sales office.
Description
The CXD2464R is a timing signal generator for
driving the LCX026, LCX016 and LCX012BL LCD
panels. This chip has a built-in serial interface circuit
which supports various XGA, SVGA and VGA signals,
and (double speed) NTSC and PAL signals through
external control from a microcomputer, etc.
64 pin LQFP (Plastic)
Features
Generates the LCX026/LCX016/LCX012BL drive
pulse.
Supports various SVGA (horizontal scanning frequency:
35 to 54kHz, vertical scanning frequency: 56 to 86Hz)
and VGA (horizontal scanning frequency: 31 to 38kHz,
vertical scanning frequency: 59 to 75Hz) signals.
Supports simple (skip scan) display of XGA signals
(1024 × 768 dots, horizontal scanning frequency:
57kHz, vertical scanning frequency: 71Hz or less,
clock frequency: 62.5MHz or less).
Supports simple (skip scan) display of SVGA
signals (800 × 600 dots).
Supports Macintosh16 signals (LCX016)
Supports PC-98 signals (640 × 400 dots, horizontal
scanning frequency: 24 to 38kHz, vertical scanning
frequency: 56 to 86Hz).
Supports NTSC and PAL signals
Line double-speed display realized with a built-in
double-speed controller (clock frequency: 33.3MHz
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
Note) Supported signals vary according to LCD panel.
Applications
LCD projectors, etc.
