NOTES:
1. AC propagation measurements should not be taken within the first 100 cycles of startup.
2. Skew measured between crosspoints of all differential output pairs under identical input and output interfaces, transitions and load conditions on any one device.
3. Skew measured is the difference between propagation delay times tPHL and tPLH of any differential output pair under identical input and output interfaces, transitions and load conditions on
any one device.
4. Skew measured is the magnitude of the difference in propagation times between any single differential output pair of two devices, given identical transitions and load conditions at identical
VDD levels and temperature.
5. All parameters are tested with a 50% input duty cycle.
6. Guaranteed by design but not production tested.
