4.3.3. MIPI CSI-2 Transmitter Clock Requirements

The CSI-2 Transmitter axi4_clk frequency should be selected such that the input video data rate achieved is the same or greater than the desired overall video data rate on the external MIPI D-PHY interface. If this is not achieved, then the data throughput will not meet requirements.

Equation 6. Derivation of the CSI-2 Transmitter axi4_clk Minimum Rate

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