Abstract

One type of synchronous timing generator for color display card withcomputer/video display mode switch consists of: 1. at least one frequency synthesizing generator; 2. at least one reference frequency; 3. at least two frequency processing structures which can take thereference frequency and convert it to specified frequency; 4. at least one video timing output terminal and one computer displaytiming output terminal to send the timing signal needed by video signalconverter and computer display timing signal; 5. at least two multiplexers, which can be controlled by the mode selectinput, switching to frequency synthesizing generator position or the twofrequency processing structures position in order to change the timingoutput signal of video display and computer display synchronously when incomputer display mode or video display mode; 6. when switching to the video mode, the two timing output can be switchedto frequency processing structures to synchronizing the two signals.
