Notes:
1. Measured from 10% to 90% of the data signal.
2. Timing difference between the differential signals.
3. Measured at crossover point of differential data signals.
4. The rising and falling edges should be smoothly transiting(monotonic)
5. Full Speed timing have a 1.5 k
pull-up to 2.8 V on the D+ (DP) data line.
6. Low Speed timing have a 1.5 k
pull-up to 2.8 V on the D- (DM) data line.
7. The maximum load specification is the maximum effective capacitive load allowed that meets the target hub VBUS droop of
330 mV.
8. All other USB Electrical Characteristics refer to USB spec Rev 1.1 7.3.2 and 7.3.3.
