Overview
WT8045 Synchronous Signal Discriminator and Power Saving Detector for Green Monitor  May 4, 1995 DESCRIPTION The WT8045 is a silicon monolithic circuit designed for synchronous signal processing and power saving detection of multi-sync display monitors, which can cope 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.
The WT8045 incorporates many functional circuits, including horizontal/vertical frequency discrimination, display mode selection, and synchronous pulse polarity and power saving detection, into this single chip IC.
WT8045 is more convenient for you to shrink the PC board size and to reduce the material and labor cost with fewer components.
FEATURES • • • • • • • Accepting two separated H&V synchronous signals with positive/ negative polarity.
Support VESA VGA (640X480, 640X400, 640X350), VESA SVGA (800X600), European SVGA (800X600), VESA new SVGA (800X600), XGA (1024X768) and 1280x1024.
Capable of processing horizontal frequency between 25KHZ to 80KHZ.
Standard IBM video mode control outputs (1024X768, 640X480, 640X400, 640X350).
Five non-standard horizontal frequency control outputs in predefined frequency range.
Power saving mode - It can detect the conditions of monitor to decide which one will be selected as following: ON/STANDBY/SUSPEND/OFF mode.
Fixed polarity outputs on both horizontal and vertical synchronous signals.
