CLK: pixel clock(像素频率) 计算方法如下: 以1920x1080p/60hz为例,total
pixel:2200,total line:1125,filed rate:60Hz,那么:PCLK = 2200*1125*60 = 148.5MHz; 1280x720p/60hz为例,total
pixel:1650,total line:750,filed rate:60Hz,那么:PCLK = 1650*751*60 = 74.25MHz; 3840x2160p/60hz YCC444为例,total pixel:4400,total
line:2250,filed rate:60Hz,那么:PCLK = 4400*2250*60 = 594MHz; 1920x1080p/60hz:total pixel:2200,total line:1125,filed rate:60Hz. PCLK = 2200 * 1125 * 60 = 148.5MHz; 148.5MHz X 3 =445.5Mhz 148.5MHz X 4 =594Mhz 148.5MHz X 5 =742.5Mhz 148.5MHz X 6 = 891Mhz PS:分辨率的实际的宽度和高度的像素: real width pixel:width/0.872727272727273 real height pixel:height/0.96 比如: HDMI为例 PCLK:像素时钟 以1920x1080p/60hz为例:1920108060=124.4MHz |
