GTL+ AC Signal Quality Specifications

Table 25, Figure 18, and Figure 19 illustrate the GTL+ signal quality specifications for the mobile
Pentium III processor. Refer to the Pentium

II Processor Developer’s Manual for the GTL+

buffer specification. The mobile Pentium III processor maximum overshoot and undershoot
specifications for a given duration of time are specified in Table 26. Contact your Intel Field Sales
representative for a copy of the OVERSHOOT_CHECKER tool. The OVERSHOOT_CHECKER
determines if a specific waveform meets the overshoot/undershoot specification. Figure 20 shows
the overshoot/undershoot waveform. The tolerances listed in Table 26 are conservative. Signals
that exceed these tolerances may still meet the processor overshoot/undershoot tolerance if the
OVERSHOOT_CHECKER tool says that they pass.
