Dp pixel clock phy ref clock 关系

WebThe D-PHY timing parameters are correctly auto-determined when video resolution is one of the listed resolutions in Table 2. The supported video resolutions are described in terms of the pixel allocations for horizontal and vertical resolutions, along with the frame rate in terms of frames per second (FPS) and pixel clock frequency (PCLK). WebAfter reading some docs, I understood that the main reference clock must be 50MHz and must be the same for MAC and PHY. I'm asking if I can use 25MHz_OUT signal output …
