Какое волновое сопротивление имеет USB кабель?

Recommended Posts

A full-speed USB connection is made through a shielded, twisted pair cable with a characteristic

impedance (Z0) of 90 Ohm +/-15% and a maximum one-way delay of 26ns. The impedance of each of the

drivers (ZDRV) must be between 28 Ohm and 44 Ohm


В экране вместе с сигнальной витой парой идут питающие провода. Цитата взята из спецификации 1.1, для 2.0 другие требования к драйверам.
