    Hello Tirthal,

    The schematic looks good. The pin connections match the pinout and within the device specifications.

    Thanks,

    Hi,

    The design connection provided in the datasheet is different from which I had done in my design, Can you please cross check the connection and let me know if I need to make update in my design.?

    Regards,

    Hello Trithal,

    What is your concern? Is it the different placements of AC caps? You only need one set of them, either on the TX or RX side. In your design the TX side has AC caps like the one in the datasheet diagram. The fact that the routing is different it doesn't matter. As long as one side has AC caps it will be fine. 

    Thanks,

    Hi,

    No My concern is regarding the Connection between the Type C connector and the MUX IC.

    Please have a look on the assignment of the Signal on the MUX IC coming from USB C connector.

    Regards,

    Hello Tirthal,

    Ok, so you have TX signals on the B pins and RX signals on the C pins, that's fine as long this works with your intended application. The protection diodes and the choke filters on the lines will not cause any issues to the mux either. 

    Were these your concerns? If not, can you please be more specific? 

    Thanks,

    Yes ,So I want to know what is the standard pin connections between the USB-C connector and MUX IC ?

    We don't have any typical requirement to connect TX signals on the B pins and RX signals on the C pins.

    I want to know what is the correct way to connect this signals ? And on which port .

    As per the datasheet I should have one pair (TX,RX) on the B0,B1 (SEL = Low)  & another pair on C0,C1 (SEL = High).

    Which in our case is incorrect ,So can you please look carefully and let us know that should we follow the datasheet ,or should we follow the current design which we have created ?

    And if we follow our design what will be the impact ,would we able to establish the connection !

    Regards,
