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