      mipi信号的clock是数据速率的一半。
      H-Blank和V-Blank跟具体的roi设置和帧率设置有关系。不过我觉得你fpga接收只要设置好最小可能值就行了。
      H-blank:180
      V-blank:25

                            降低帧率的话,V-Blanking会加大。比如默认是1080p@60fps,对应V-Total=V-Active+V-Blanking=1080+25;那么配置成30fps的时候,V-Total会配置为原来的2倍,增加的全部会加到V-Blanking中。

                                      @canglin 应该是891Mbps/lane; csi_clk应该是这个值的一半,因为是双沿的。
