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.
NOTE: All parameters measured at ƒ 250MHz unless otherwise noted.
NOTE 1: Measured from the differential input crossing point to the differential output crossing point.
NOTE 2: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltage, same temperature, same frequency and
with equal load conditions. Using the same type of inputs on each device, the outputs are measured at the differential cross points.
NOTE 4: Defined as skew between outputs at the same supply voltages and with equal load conditions. Measured at the output differential
cross points.
NOTE 5: Measurement taken from differential waveform.
NOTE 6: Measured from -150mV to +150mV on the differential waveform (derived from Qx minus nQx). 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.
See Parameter Measurement Information Section.
NOTE 7: Measurement taken from single ended waveform.
NOTE 8: Defined as the maximum instantaneous voltage including overshoot. See Parameter Measurement Information Section.
NOTE 9: Defined as the minimum instantaneous voltage including undershoot. See Parameter Measurement Information Section.
NOTE 10: Measured at crossing point where the instantaneous voltage value of the rising edge of Qx equals the falling edge of nQx.
See Parameter Measurement Information Section
NOTE 11: 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. See Parameter Measurement Information Section.
NOTE 12: Defined as the total variation of all crossing voltage of rising Qx and falling nQx. This is the maximum allowed variance in the
V
CROSS
for any particular system. See Parameter Measurement Information Section.
NOTE 13: Qx, nQx output measured differentially. See Parameter Measurement Information for MUX Isolation diagram.
