DS90UB960-Q1: Regarding Interfacing of cameras

Part Number: DS90UB960-Q1
Other Parts Discussed in Thread: DS90UB933-Q1, DS90UB953-Q1, DS90UB913A-Q1

Hello sir,

The datasheet of DS90UB960-Q1  says that we can connect up to 4 cameras @2 MP. If I want to connect 2 cameras @4 MP. then it is possible or not? What is the calculation behind this?

And how we choose serializer for this deserializer as datasheet shows that it is compatible with DS90UB953-Q1, DS90UB913A-Q1, and DS90UB933-Q1. Like I want to make a surrounding view camera for our autonomous vehicle then what are the hard requirements in choosing serializer and deserializer. What are the main factors and reasons behind this?

Regards,

Harsh Garg

    Harsh,
    The DS90UB960 is a deserializer hub capable of connecting serialized camera data from 4 independent video streams. It can support receiving data from imagers at full HD 1080p/2MP/60-Hz frame rate when used with a DS90UB953 serializer. It is not just a matter of MP but it also depends on fps (frames per sec), resolution etc.

    The 960 is also compatible with the older generation FPD-Link III serializers such as 913A, 933 but it operates with basic functionality - it needs to be used in the RAW mode and not CSI-2 mode with these serializers. You can request a copy of the latest 960 documentation from the TI website on the 960 product page.

    Hi Palaniappan,

    We have to connect deserializer between serializer and deserializer hub ??

    Like in above picture they connect 954 between 953 and 960. 

    If I want to connect 4 cameras with 953 serializers then I have to connect it with only deserializer hub or if have to connect first with deserializer then with deserializer hub ??

    You can connect the 960 deserializer hub to the 4 953's and cameras directly. This picture above is not a connection diagram, but rather a high level overview of the FPD-Link ADAS product portfolio where the 954 is just shown as a CSI-2 capable deserializer.
    If you would like to learn more about 960, you can request a copy of the product documentation on the TI website.

    We also have FPD-Link training material and video modules available on the TI site at the links provided below.

    Hi,

    I have some more questions please help me out.
    If two CMOS image sensors are connected to an ISP then we can connect ISP directly to serializer DS90UB953-Q1?.

    The image sensor is connected to the serializer, and the ISP is connected to the deserializer.
    You can refer to the datasheet for application information.

    No, Not like this way. I want to connect two CMOS Image sensor with an ISP, then ISP to serializer, then using FPD-III link serializer to deserializer.
    Is it possible to make this type of architecture??

    Yes this can work. The ISP can place the data into separate virtual channels to tell the processor which packet belongs to which camera or image sensor.
