NOTES:
1. All voltages measured from local ground, unless otherwise specified.
2. All timings use a capacitive load of (CL) to ground of 50pF, unless otherwise specified.
3. Full speed timings have a 1.5k
4. Low speed timings have a 1.5k
5. Measured from 10% to 90% of the data signal.
6. The rising and falling edges should be smoothly transitioning (monotonic).
7. Timing differences between the differential data signals.
8. Measured at crossover point of differential data signals.
9. The maximum load specification is the maximum effective capacitive load allowed that meets the target HUB VBUS droop of 330mV.
