NOTES:
1. Driver output resistance under steady state drive is spec’d 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. Full Speed Data Rate has minimum of 11.97 Mbps and maximum of 12.03 Mbps.
8. Low Speed Data Rate has a minimum of 1.48 Mbps and a maximum of 1.52 Mbps.
