NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
29. Measured using a 500 mV source, 50% duty cycle clock source. All outputs loaded with 50 W to VCC − 2.0 V. Input edge rates 40 ps
(20% − 80%)
30. See Figure 6. tSKEW = |tPLH − tPHL| for a nominal 50% Differential Clock Input Waveform.
31. Within−Device skew is measured between outputs under identical transitions and conditions on any one device.
32. Device−to−device skew for identical transitions at identical VCC levels.
33. VINPP (MAX) cannot exceed VCC − VEE (applicable only when VCC−VEE < 2600 mV).
34. Additive RMS Jitter with 50% duty cycle clock signal at 10 GHz.
35. Additive Peak−to−Peak data dependent jitter with NRZ PRBS 231−1 data at 10 Gb/s.
