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
