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 using a VINPPmin source, 50% duty cycle clock source. All output loading with external 50 W to VCC 2 V. Input edge rates 40 ps
(20% 80%).
12.Output voltage swing is a singleended 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 crosspoint of the inputs to the crosspoint of the outputs.
14.Additive RMS jitter with 50% duty cycle clock signal.
15.Additive PeaktoPeak 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 singleended measurement operating in differential mode.
