| Abstract: | With the speedy development of LCD and other flat panel display technology,Digital Video Interface gradually being widely applied.For compatible with the traditional VGA＇s analog interface,this paper uses the Intersil＇s ISL98003 as the analog-digital conversion chip,and uses the single-chip uPSD3234 as control chip,to achieve the converter design which change analog video signal into digital video signal.ADC and PLL circuit are built in the ADC,which change analog video signals into digital signals,and also revise the display value of CRT,in order to get the gray-scale signal to fit the pixel characteristics of LCD. |
