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.
