The minimum V
The symbol OV
The symbols for timing specifications follow the pattern of t
and t
the input (I) to go invalid (X) with respect to the time the USB clock reference (K) goes high (H). Also, t
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.
All timings are in reference to the USB clock, USBDR_CLK.
All signals are measured from OV
signaling levels.
Input timings are measured at the pin.
For active/float timing measurements, the high impedance 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.
