The speed of DS90UB960 is set to 1600M to Orin, and there is no picture in the Orin.How to solve it?

Hi,
The data path is as following.
camera sensor---------->DS90UB953---------->DS90UB960---------->Orin
If I set the speed of DS90UB960 to 1200M, the Orin can capture the picture of the camera.And if I set the speed of DS90UB960 to 1600M,there is no picture caputured. I want to set the speed to 1600M because of the need of 4 camera.
Can you tell me how to solve it?
Thanks

Did you modify pix_clk_hz/serdes_pix_clk_hz in dts??
If don’t boost the clocks to try. If still failed get the trace log to check if more informaiton.
