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.
Measured using 26.5625MHz crystal as the input reference source. If using an external reference input, use a low phase noise source. With an
external reference, the phase noise will follow the input source phase noise up to about 1MHz.
