Hi Team,

Here is my customer TXB0304 data layout trace length, which is over 3414 distance, do we have layout guide to give recommendation for  data trace length condition? 
 

Best regards,

    Hi Daisy,

    PCB signal trace-lengths must be kept short enough so that the round-trip delay of any reflection is less than the one-shot duration, approximately 10 ns, ensuring that any reflection encounters low impedance at the source driver.

    Short trace-lengths should be used to avoid excessive loading.The TXB device is autobidirectional device which doesn’t have enough drive strength to overcome excessive resistive / cap loading so traces should be kept as short as possible.

    Thanks!
