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.
11. Measured by forcing VINPP(min) from a 50% duty cycle clock source. All loading with an external RL = 50 W to VCC – 2.0 V. Input edge rates
40 ps (20% 80%).
12.Skew is measured between outputs under identical transitions and conditions @ 0.5 GHz. Duty cycle skew is measured between differential
outputs using the deviations of the sum of Tpw and Tpw+ @ 0.5 GHz.
13.Additive RMS jitter with 50% duty cycle clock signal.
14.Additive peaktopeak data dependent jitter with input NRZ data at PRBS23.
15.Input and output voltage swing is a singleended measurement operating in differential mode.
