1. Output skew defined for identical output transitions.

2. Process skew is valid for VCC = 5.0V ±5%.

3. Parameters guaranteed by tSK(P) and tr, tf specification limits.

4. Clock stability is the period variation between two successive rising edges.

5. For series terminated lines. See Applications section for FMAX enhancement techniques.

6. All AC specifications tested driving 50Ω series terminated transmission lines at 80MHz.
