This table lists the general timing parameters of the USB-ULPI interface.
The following two figures provide the AC test load and signals for the USB, respectively.

USB clock cycle time
Input setup to USB clock—all inputs
Input hold to USB clock—all inputs
USB clock to output valid—all outputs
Output hold from USB clock—all outputs
Notes:
1. The symbols used for timing specifications follow the pattern of t
2. All timings are in reference to USB clock.
3. All signals are measured from NVDD/2 of the rising edge of USB clock to 0.4  NVDD of the signal in question for 3.3-V
4. Input timings are measured at the pin.
5. For purposes of active/float timing measurements, the Hi-Z or off-state is defined to be when the total current delivered
