Dear TI Support Partners:
我这边有看到948的datasheet上描述:170 MHz for WUXGA (1920x1200) and 1080p60 Resolutions with 24-bit Color Depth。请问如果我推4032x756@40fps的屏,clk设149MHz,948能支持吗?

我们可以直接计算下4032x756@40fps 需要的PCLK的时钟频率:以15%的blanking time计算的话
4032*756*40*(1+15%)=140.2Mhz<149Mhz.
所以可以149Mhz是支持的。或者如果需要更大余量的话,PCLK的值可以稍大些,1080p60理论上需要148.5Mhz。
