unless noted otherwise.
NOTE 1: Defined as the time difference between the input reference clock and the average feedback input signal, when the PLL is locked and
the input reference frequency is stable.
NOTE 2: These parameters are guaranteed by characterization. Not tested in production.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 4: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at V
