W NOTE 1: All parameters measured at 200MHz unless noted otherwise. All outputs terminated with 50 to VDDO/2.
NOTE 2: Defined as skew within a bank of outputs at the same supply voltages and with equal load conditions.
NOTE 3: Defined as skew across banks of outputs at the same supply voltages and with equal load conditions.
NOTE 4: Defined as skew across banks of outputs operating at different frequency with the same supply voltages
and equal load conditions.
NOTE 5: Defined as the skew at different outputs on different devices operating at the same supply voltages and
with equal load conditions.
NOTE 6: These parameters are guaranteed by characterization. Not tested in production.
