Notes:

4. Defined as skew between outputs at the same supply voltage and with equal load conditions; measured at the output differential crossing points.

5. Output-to-output skew is only defined for outputs in the same PLL bank [A:B, C:D] with the same output type setting.

6. All phase noise measurements were taken with an Agilent 5052B phase noise system.
