NOTE 1: All parameters measured at 167MHz and VPPmin unless noted otherwise.
All outputs terminated with 50Ω to VDDO/2.
NOTE 2: Defined as skew within a bank of outputs at the same 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 the skew at different outputs on different devices operating at the same supply voltages
with equal load conditions.
NOTE 5: These parameters are guaranteed by characterization. Not tested in production.
