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 horizont...
