Notes:
5.
All phase-noise measurements were taken with an Agilent 5052B phase-noise system.
6.
Defined as skew between outputs at the same supply voltage and with equal load conditions; Measured at the output differential crossing points.
7.
Ref_IN driven with a low-noise source ClockWorks SM802001 programmed for a 15MHz CMOS output. Phase noise will track the input phase
noise up to about 1MHz offset frequency.
