NOTE 1: Measured from VDD/2 of the input to VDDO/2 of the output.
NOTE 2: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 3: Defined as skew between outputs on different devices operating a the same supply voltages and
with equal load conditions. Using the same type of input on each device, the output is measured at VDDO/2.
NOTE 4: Phase jitter is dependent on the input source used.
NOTE 5: These parameters are guaranteed by characterization. Not tested in production.
