TS5MP645: Multiple TS5MP645 connected as cascade

TS5MP645: How to use TS5MP645 as 2 inputs and 1 output

Part Number: TS5MP645
Other Parts Discussed in Thread: TS5MP646

Hi team,

According to below figure, input data is fixed by processor and we can select which Mipi module we use. but our customer wants to realize that input data is selectable and output data is fixed. It is like opposite way. Is it impossible to use such a way? if impossible, do you have any other recommendation devices?

Thanks,

    Masayuki,

    Please see this post I found searching e2e for "TS5MP645 bi directional"  

    Thank you,

    Hi Adam,

    Thank you for your reply. I understood the TS5M645 was also be able to use bi directional. but how do we check that the switch can use bidirectional by the datasheet?  Our customer wants to get an evidence.

    Thanks,

    Masayuki

    Masayuki,

    You can see in the diagram you attached that the arrows point both directions which indicates signals can go in either direction.

    Also you can see that there aren't any Voh or Vol specs in the electrical specifications table showing that there is not a buffered output.

    This is a passive FET switch and either the drain or the source can be the input or output.

    Thank you,
    Adam

    Hi Adam, 

    Our customer thinks that the CLK direction and DATA direction should be same if they use CSI-2. According to the pin function of the datasheet,  any clock pin is differential I/O. That's why I'll explain it to customer that the device can use both directions. Is it correct in my understanding?

    In addition, do you have any plan to make an automotive version for TS6MP645?

    Thanks,

    Masayuki

    Masayuki,

    You are correct that any pin of the TS5MP646 can be used for either clock signal or data signal. The device doesn't have any intelligence built in or any drive capability. You can think of this device as a wire with some loss.

    I will let our product definers know that you are interested in an automotive version of this device.

    Thank you,
    Adam
