Hi team,
Our customer would like to know what is the trace impedance (in ohms) for the front‑end eUSB 2 and the back‑end USB 2?

Thanks.
Best Regards,
William Lai

HI William:
For the eUSB2 differential trace, we recommend an 85ohm differential impedance.
For the USB2 differential trace, we recommend an 90ohm differential impedance.
