1. Guaranteed by design, not tested in production.

2. Measured from 10% to 90% of the data signal. For more detailed informations, please refer to USB Specification - Chapter

7 (version 2.0).

3. No external termination series resistors are required on USB_DP (D+) and USB_DM (D-), the matching impedance is

already included in the embedded driver.
