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.
10.Measured by forcing VINPPmin with 50% duty cycle clock source and VCC 1400 mV offset. All loading with an external RL = 100 W across
“D” and “D” of the receiver. Input edge rates 150 ps (20%80%).
11. See Figure 13 differential measurement of tskew = |tPLH tPHL| for a nominal 50% differential clock input waveform @ 250 MHz. 12.Input voltage swing is a singleended measurement operating in differential mode.
13.RMS jitter with 50% duty cycle input clock signal.
14.Deterministic jitter with input NRZ data at PRBS 2231 and K28.5.
15.Skew is measured between outputs under identical transition @ 250 MHz.
16.Crosstalk induced jitter is the additive deterministic jitter to channel one with channel two active both running at 622 Gb/s PRBS 223 1 as
an asynchronous signals.
17.The worst case condition between Q0/Q0 and Q1/Q1 from either D0/D0 or D1/D1, when both outputs have the same transition.
