AC Electrical Characteristics
Table 3. HCSL AC Characteristics, VDD = 3.3V±5%, TA = 0°C to 70°C
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: Current adjust set for VOH = 0.7V. Measurements refer to PCIEX outputs only.
NOTE: Characterized using an RREF value of 950 resistor.
NOTE 1: Measured from the differential input cross point to the differential output crossing point.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the differential output
cross point.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 4: Defined as skew between outputs on different devices operating at the same supply voltage, same frequency, same temperature and
with equal load conditions. Using the same type of inputs on each device, the outputs are measured at the differential cross point.
NOTE 5: Output Drift is measured as the change in the time placement of the differential cross point for each output on a given device due to
a change in temperature and supply voltage. Measured at the differential cross point.
NOTE 6: Measurement using RREF = to 950, RLOAD = to 50.
NOTE 7: Measurement taken from single-ended waveform.
NOTE 8: 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 9: 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 10: Defined as the total variation of all crossing voltage of rising Qx and falling nQx. This is the maximum allowed variance in the
VCROSS for any particular system. See Parameter Measurement Information Section.
NOTE 11: Measurement taken from differential waveform.
NOTE 12: Measurement 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.
NOTE 13: Assuming 50% input duty cycle. Data taken at
≤ 200MHz, unless otherwise specified.
