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 (TYP) from a 50% duty cycle clock source. All loading with an external RL = 50 W to VCC.
Input edge rates 40 ps (20% 80%).
12.Duty cycle skew is measured between differential outputs using the deviations of the sum of Tpw and Tpw+ @1 GHz.
13.Device to device skew is measured between outputs under identical transition @ 1 GHz.
14.Additive RMS jitter with 50% duty cycle clock signal at 10 GHz.
15.Additive peaktopeak data dependent jitter with input NRZ data at PRBS 2^231.
16.VINPP (MAX) cannot exceed VCC VEE. Input voltage swing is a singleended measurement operating in differential mode.
