PENTIUM® III XEON™ PROCESSOR AT 600 MHz to 1 GHz with 256KB L2 Cache

SIGNAL QUALITY

Figure 13. Maximum Acceptable Overshoot/Undershoot Waveform

1,2,3,4,5,6,7,8

NOTES:

1. Overshoot Magnitude and Undershoot Magnitude are absolute values and should never exceed 2.3V under any circumstances.

2. Overshoot is measured relative to V

3. Undershoot is measured relative to V

TT.

4. Overshoot/Undershoot Pulse Duration is measured relative to 1.635V.

5. Rinback below V

cannot be subtracted from Overshoots/Undershoots.

6. Lesser Undershoot does not allocate longer or larger Overshoot. Lesser Overshoot does not allocate longer or larger Undershoot.

7. OEM's are encouraged to follow Intel provided layout guidelines.

8. All values specified by design characterization.

4.3 Non-GTL+ Signal Quality Specifications

There are three signal quality parameters defined for non-AGTL+ signals: Overshoot/Undershoot, Ringback, and Settling

Limit. The three signal quality parameters are shown in Figure 14 for the non-AGTL+ signal group at the processor core

pads. Overshoot/Undershoot shown in Figure 14 is for illustrative purposes only to help explain Ringback and Settling

Limit. Refer to Figure 13 for an illustration of Overshoot/Undershoot specifications.
