FPD LINK-Suggestion needed: SerDes application for one camera send video to 2 ECU

Hi, Support team

I'm currently investigating an application that one camera provide the video steaming for 2 ECU for redundancy purpose. If ECU 1 is fail, it can still streaming video to ECU 2.

Do you have any suggestion on products could support this?

    Hello,

    Thank you for reaching out. The replicate mode of our deserializers would be a good option to support this application.

    The DS90UB960 deserializer has two CSI output ports with the second port having the ability to output a replicated copy of the first port. This means that each ECU would be connected to its own CSI port and receive identical data. Alternatively, if the chosen camera has a lower bandwidth, the DS90UB954 deserializer can also operate in replicate mode to generate two identical streams of data. However, since the DS90UB954 only has one CSI port the 4-lane port will be split into two 2-lane ports each with their own clock. Since only 2 data lanes will be available, only lower bandwidth applications are supported.

    If you have already chosen a camera and know what bandwidth the application needs to support, I can help determine which deserializer and partner serializer would be appropriate.

    Regards,
