What is difference between CSI-2 non-Sync back channel,CSI-2 Sync back channel, RAW10, RAW12 HF and RAW12 LF.

Are they related with Camera selection?

    Alex,

    yes, it is related with your system video transmission request.

    1. For CSI2 mode or RAW mode, it is dependent on which sterilizer is selected. if ub933/913a is used, you should set RAW mode. if ub935/953 is used, you must use the CSI2 mode.

    2. For the sync. CSI2 and non-sync. CSI2 mode, it is different with how you select the refer. clock source to serializer's PLL. If sync. mode is used, it means the Serializer's PLL is sourced from the UB954's external XO. please check tabel6 in ub953 d/s for different clocking mode settings.

    best regards,

    Steven
