4.3.3. MIPI CSI-2 Transmitter Clock Requirements

Select the MIPI CSI-2 transmitter axi4s_clk frequency 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 not, the data throughput does not meet requirements.
Equation 5. Derivation of the CSI-2 Transmitter axi4_clk Minimum Rate

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