Part Number: TUSB321

Hi, Support Team

We saw the TUSB321 of datasheet as figure 4. about DFP Mode schematic.

Why

C0P to TXN1 and C0N to TXP1? 

C1P to RXN1 and C1N to RXP1?

is reverse or not?

if any suggestion, Please advise me.

Thanks,

Best regards,

Lawrence

    Hi Lawrence,

    The data lines are swapped going into the MUX because CC1 and CC2 are swapped going to the TUSB321.

    It is ok to use this configuration if it is more convenient for your design. If you do not swap CC1 and CC2, then you need to keep TX1/RX1 routed to B0/B1 and TX2/RX2 routed to C0/C1.

    Best,
