This Figure shows the PL live video clocking of the DisplayPort controller.

 

RECOMMENDED:   When using live clock input from the PL, the VTC clock source selection must be selected as live input from the PL. Since the live interface also interfaces with the video processing pipeline, the same live clock is used by the rest of the pipeline in the PS.

Note:   While using the live video interface, the user must select VPLL as the input reference clock for the pixel clock or the live clock input from PL.

This Figure shows the details of the live audio clocking interface.
