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.

12.Output voltage swing is a single−ended measurement operating in differential mode.
13.Skew is measured between outputs under identical transitions and conditions. Duty cycle skew is defined only for differential operation when
the delays are measured from cross−point of the inputs to the cross−point of the outputs.
14.Additive RMS jitter with 50% duty cycle clock signal.
15.Additive Peak−to−Peak data dependent jitter with input NRZ data at PRBS23.
16.Crosstalk is measured at the output while applying two similar clock frequencies that are asynchronous with respect to each other at the
inputs.
17.Input voltage swing is a single−ended measurement operating in differential mode.
