Hi ,

Please recommend one or more solution can match our requirement.

Can use 1*4lane CSI to DS90UB964, support 4*2MP cameras? Can DS90UB964 support the above features？

    Hi Gavin,

    The arrows in the diagram are a little bit confusing, since the video data should be sent from the Camera->SER->DES->Processor. But in terms of quad-hub deserializers, the choices are:

    1. DS90UB960-Q1
    2. DS90UB962-Q1
    3. DS90UB964-Q1

    All of these quad hub deserializers support PoC, external framesync, have an INTB pin to alert the processor of interrupts, and allow GPIO and I2C information to be passed in both directions from the Processor->DES->SER->Camera or Camera->SER->DES->Processor. They all also have at least CSI-2 output port that can be routed up to x4 data lanes. 

    The 960 is a good general purpose quad hub deserializer that can connect to Parallel or CSI-2 interface serializers. The 962 is the lower-cost version that has x1 CSI-2 output port, instead of the x2 in the 960, and supports a lower video throughput at each RX Port. The 964 is only compatible with Parallel interface serializers, such as the 913A or 933, and supports lower video throughput at the RX Ports.

    What serializer is being used on the camera module? The deserializer needs to be connected to a serializer and it would help knowing what the camera's video interface is, before I give a recommendation.

    Also, what is the video throughput of each camera? Video throughput can be calculated using the equation:

    Video Throughput = HActive x VActive x (Frame Rate) x Bits-per-pixel x Overhead(Assume 15-25% is unknown)

    Best,
