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
