Notes:
1. Driver output resistance under steady state drive is specified at 28 ohms at minimum and 43 ohms at
maximum.
2. Timing difference between the differential data signals.
3. Measured at crossover point of differential data signals.
4. Measured at 50% swing point of data signals.
5. Measured from last crossover point to 50% swing point of data line at leading edge of EOP.
6. Measured from 10% to 90% of the data signal.
7. High-speed Data Rate has minimum of 479.760 Mb/s and maximum of 480.240 Mb/s
8. Full-speed Data Rate has minimum of 11.97 Mb/s and maximum of 12.03 Mb/s.
9. Low-speed Data Rate has a minimum of 1.48 Mb/s and a maximum of 1.52 Mb/s.
