FSB Signal Quality Specifications and Measurement
Guidelines
Various scenarios have been simulated to generate a set of AGTL+ layout guidelines which are
available in the Mobile Intel Pentium 4 Processor-M and Intel 845MP/845MZ Chipset
Platform Design Guide.
Table 26 and Table 27 provides the signal quality specifications for all processor signals for use in
simulating signal quality at the processor core silicon (pads).
Mobile Celeron processor maximum allowable overshoot and undershoot specifications for a given
tolerance for low-to-high transitions and Figure 25 shows ringback tolerance for high-to-low
transitions.
NOTES:
1. All signal integrity specifications are measured at the processor silicon (pads).
2. Unless otherwise noted, all specifications in this table apply to all mobile Celeron processor frequencies.
3. Specifications are for the edge rate of 0.3 - 4.0 V/ns.
4. All values specified by design characterization.
5. Please see Section 3.3 for maximum allowable overshoot.
6. Ringback between GTLREF + 10% and GTLREF - 10% is not supported.
7. Intel recommends simulations not exceed a ringback value of GTLREF
± 200 mV to allow margin for other
sources of system noise.
