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
