Notes:
1. The symbols used 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 NVDD/2 of the rising edge of USB clock to 0.4
× NVDD of the signal in question for 3.3-V
signaling levels.
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
through the component pin is less than or equal to the leakage current specification.
