Notes:
1. The symbols for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tUSIXKH symbolizes USB timing (US) for
the input (I) to go invalid (X) with respect to the time the USB clock reference (K) goes high (H). Also, tUSKHOX symbolizes
USB timing (US) for the USB clock reference (K) to go high (H), with respect to the output (O) going invalid (X) or output hold
time.
2. All timings are in reference to USB clock.
3. All signals are measured from OVDD/2 of the rising edge of the USB clock to 0.4 × OVDD of the signal in question for 3.3 V
signaling levels.
4. Input timings are measured at the pin.
5. For active/float timing measurements, the Hi-Z or off-state is defined to be when the total current delivered through the
component pin is less than or equal to that of the leakage current specification.
