Hi Abraham,

The PCLK refers to the equivalent pixel clock frequency. The PCLK can be calculated by using (horizontal total x vertical total x refresh rate. For example for 1080p, you may use 2200x1125x60 = 148.5MHz. If you want to measure PCLK, you may measure directly from the OLDI signals pin CLK1± and CLK2±.

Hope this helps. Let me know if you have further questions.
