TUSB2077A: Trace Length

Ray Vincent Aranzaso

Part Number: TUSB2077A

Hi,

Good Day.

The customer is using the TUSB2077A and he sees that the recommender trace length is 8 inches, now how bad would it be to route the trace a little much longer, like around 10 or 11 inches without a bad interference?

Please advise. Thank you very much.

Best Regards,

for USB full speed, 11 in should be ok.

Hi Brian,

Good Day.

Just out of curiosity, in the case that it could extend longer, let’s say up to 15 inches, is that also okay?

There is a lot of play in this design due to the distance and he needs to make sure. Thank you very much.

Best Regards,
