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