摘　　要：随着以LCD和其他数字平板显示技术的飞速发展,数字视频接口逐渐地被人们广泛应用。本文选择Intersil公司的ISL98003作为模数转换芯片,采用单片机uPSD3234控制,完成了模拟转数字视频信号转换器的设计。模数转换器内置ADC及PLL电路,将模拟的视频信号转化成数字信号,并针对CRT显示的值进行校正,得到适合LCD象素特性的灰度信号。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.
