NOTES:
1. All voltages measured from local ground, unless otherwise specified.
2. All timings use a capacitive load of 50pF, unless otherwise specified.
3. Low speed timings have a 1.5k pull-up to 2.8V on the D– data line.
4. Measured from 10% to 90% of the data signal.
5. The rising and falling edges should be smoothly transitioning (monotonic).
6. Timing differences between the differential data signals.
7. Measured at crossover point of differential data signals.
8. Capacitive loading includes 50pF of tester capacitance.
