Note 1. Outputsloadedwith50Ω-t-ground.

Note 3. Differential propagation delay is defined as the delay from the crossing point of the differential input signals to the crossing point of the

differential output signals.

Note 5. OEset-uptimeisdefinedwithrespecttotherisingedgeoftheclock.OEHIGH-to-LOWtransitionensuresoutputsremaindisabledduringthe

next clock cycle. OE LOW-to-HIGH transition enables normal operation of the next input clock.
