NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the
device is mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after
thermal equilibrium has been reached under these conditions.
All parameters measured at f_OUT unless noted otherwise.
NOTE 1: Measurement taken from differential waveform.
NOTE 2: t_STABLE is the time the differential clock must maintain a minimum ±150mV differential voltage after rising/falling edges before it
is allowed to drop back into the Vrb ±100mV range. See Parameter Measurement Information Section.
NOTE 3: Measurement taken from single-ended waveform.
NOTE 4: Defined as the maximum instantaneous voltage including overshoot. See Parameter Measurement Information Section.
NOTE 5: Defined as the minimum instantaneous voltage including undershoot. See Parameter Measurement Information Section.
NOTE 6: Measured at the crossing point where the instantaneous voltage value of the rising edge of Q[Ax:Ex] equals the falling edge of
nQ[Ax:Ex].
NOTE 7: Refers to the total variation from the lowest crossing point to the highest, regardless of which edge is crossing. Refers to all
crossing points for this measurement.
NOTE 8: Defined as the total variation of all crossing voltages of rising Q[Ax:Ex] and falling nQ[Ax:Ex]. This is the maximum allowed
variance in Vcross for any particular system.
NOTE 9: Measured from -150mV to +150mV on the differential waveform (derived from Q[Ax:Ex] minus nQ[Ax:Ex]). The signal must be
monotonic through the measurement region for rise and fall time. The 300mV measurement window is centered on the differential zero
crossing.
