NOTES:
1. Under no circumstances should the sum of the Max V
CCT
and absolute value of the Overshoot/Undershoot
voltage exceed 1.78 V.
2. Activity factor of 1 represents the same toggle rate as the 133-MHz clock.
3. Ringbacks below V

cannot be subtracted from overshoots. Lesser undershoot does not allocate longer or
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.

Non-AGTL Signal Quality Specifications
Signals driven to the Mobile Intel Celeron Processor should meet signal quality specifications 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 Table
40. Ringback must not exceed the CMOS V
