WT8043
Synchronous Signal discriminator
for Multi-Sync Display Monitor
Jan. 30, 1996
Description
The WT8043 is a silicon monolithic circuit designed for synchronous signal
processing of multi-sync display monitors capable of coping with many kinds of PC's
and workstations. It can be applied to display monitors supporting standard IBM
VGA, VESA super VGA and IBM 8514/A video modes. It can also be used in other
high-end display monitors supporting non-standard video modes with user-defined
horizontal/vertical frequency ranges.
WT8043 incorporates many functional circuits, horizontal/vertical frequency
discrimination, display mode selection, and synchronous pulse polarity detection, into
a single chip. Therefore, by using WT8043, monitor makers can shrink the PC board
size, reduce the material cost with fewer components, and reduce labor cost as well.
Features
• Accepting separate H&V Synchronous signals with any polarities
• Support VESA VGA (640x480, 640x400, 640x350), VESA SVGA (800x600),
European SVGA (800x600), VESA new SVGA (800x600), XGA (1024x768)
and 1280x1024.
• Also including NEC (24K) mode, 3 VESA New 75Hz timing modes and Apple
MAC II (35k) mode.
• Capable of processing horizontal frequency from 25KHz to 80KHz
• Capable of processing vertical frequency from 50Hz to 120Hz
• Standard IBM video mode control outputs (1024x768, 640x480, 640x400,
640x350)
• Six non-standard horizontal frequency control outputs with predefined frequency
range. (users can define their own horizontal frequency range)
• Fixed polarity horizontal and vertical synchronous signals output
• Power supply voltage: 5V, but mode select control output and frequency
discrimination control output, these open collector outputs can be combined with
pull high resistor, pull up to 12V.
Application
• Auto size control for Multi-Sync Display Monitors
