问 初步是打算用ADV7125，但是#SYNC应该怎么得到亚？，还有VGA的HSYNC跟VSYNC需要什么电路转换亚？
数字RGB信号有：R8, G8, B8, PCLK(Pixel clock), LCLK( Line clock, as HSYNC ), FCLK(Frame clock as "VSYNC"), BIAS(AC bias that signals), LCD_CS以及一个VSYNC输入(Refresh sync signal from the LCD panel with internal frame buffer.) 答 1: 用HC541就可以了 答 2: 不是吧？HC541不是八路三态收发缓冲器么？那要怎么接亚？
