NOTES:
1. Under no circumstances should the sum of the Max V
voltage exceed 1.78 V.
2. Activity factor of 1 represents the same toggle rate as the 133-MHz clock.
3. Ringbacks below V
larger overshoot.
4. Ringbacks above ground cannot be subtracted from undershoots. Lesser overshoot does not allocate
longer or larger undershoot.
5. System designers are encouraged to follow Intel provided AGTL layout guidelines.
6. All values are specified by design characterization and are not tested.

Non-AGTL Signal Quality Specifications

Signals driven to the LV Intel Pentium
to ensure that the processor reads data properly and that incoming signals do not affect the long-
term reliability of the processor. The overshoot and undershoot specifications for non AGTL
signals are shown in
