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:
1920*1080
real width pixel:1920/0.872727272727273 = 2200
real height pixel:1080/0.96 = 1125
