Characterized with outputs at the same frequency using the loop filter components for the mid loop bandwidth.
Refer to VCXO-PLL Loop Bandwidth Selection Table.
NOTE 1: Please refer to the Phase Noise Plot.
NOTE 2: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load condtions.
Measured at the output differential cross points.
