Note 1: All voltages are measured from the local ground potential, unless otherwise specified.

Note 2: All timing use a capacitive load (CL) to ground of 50pF, unless otherwise specified.

Note 3: Full speed timings have a 1.5KΩ pull-up to 2.8 V on the D+ data line.

Note 4: Measured from 10% to 90% of the data signals.

Note 5: The rising and falling edges should be smoothly transiting (monotonic).

Note 6: Timing differences between the differential data signals.

Note 7: Measured at crossover point of differential data signals.

Note 8: These are relative to the 14.318 MHz crystal.
