Part Number: DS90UB960-Q1

Tool/software:

Hi

4-channel 1920x1536 cameras UB953----->UB960----4lane--->SOC（CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS）。

If there is only one path, the camera can reach 30fps
If there are 4 channels, the frame rate can only be lower than 1-5 fps.

UB960 reg  0x1f = 00； 

dump UB960 reg：

0x4c=1

    HI GG,

    Looks like there is lots of errors on register 0x4E. Think that you are hitting the bandwidth limit of the device. Can you run with 2- or 3 cameras? If this works this means you are above the bandwidth limit. 

    Can you complete the following information in the excel sheet that I will send via chat?
