4.3.2. MIPI CSI-2 Receiver Clock Requirements

The MIPI 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 not, data loss occurs.
Equation 4. Derivation of the CSI-2 Receiver axi4_clk Minimum Rate

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