NOTE 1: Measured using Aeroflex PN9500.
NOTE 2: Measured using Wavecrest SIA-3000.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at VDD/2.
NOTE 4: These parameters are guaranteed by characterization. Not tested in production.
NOTE 5: This is the frequency error contributed by the oscillator and must be added to the frequency timing error from the
crystal to obtain the total frequency stability. See Frequency Stability in the Application Information Section.
