Hi team,
We are under FA process of DS90UB948-Q1, and there is a requirement to measure PCLK. What is PCLK and how can we measure it?
Thank you!

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.
