4.3.2. MIPI CSI-2 Receiver Clock Requirements

The CSI-2 Receiver axi4_clk frequency must ensure that the output video data rate is the same or greater than the peak burst data rate on the external MIPI D-PHY interface. If this is not achieved, then data loss will occur.

Equation 5. Derivation of the CSI-2 Receiver axi4_clk Minimum Rate

Intel recommends that you allow at least 10% buffer above the minimum clock rate calculated for this clock.
