Table 5B. HCSL AC Characteristics, VDD = 3.3V ± 0.3V, TA = -40°C to 85°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 1: Measured from the differential input crossing point to the differential output crossing point.

NOTE 2: Defined as skew between input paths on the same device, using the same input signal levels, measured at one specific output at the

differential cross points.

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 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 5: Measurement taken from differential waveform.

NOTE 6: Measurement from -150mV to +150mV on the differential waveform (derived from Q minus nQ). 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 7: TSTABLE 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 ±100 differential range. See Parameter Measurement Information Section.

NOTE 8: Measurement taken from single-ended waveform.

NOTE 9: Defined as the maximum instantaneous voltage including overshoot. See Parameter Measurement Information Section.

NOTE 10: Defined as the minimum instantaneous voltage including undershoot. See Parameter Measurement Information Section.

Notes continued on next page.

NOTE 11: Measured at crossing point where the instantaneous voltage value of the rising edge of Q equals the falling edge of nQ.
