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.
