System Bus 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 27
and
Table 28
provides the signal quality specifications for all processor signals for use in
simulating signal quality at the processor core silicon (pads).
Mobile Intel Pentium 4 Processor-M maximum allowable overshoot and undershoot specifications
for a given duration of time are detailed in
Table 29
through
Table 32
.
Figure 26
shows the system
bus ringback tolerance for low-to-high transitions and
Figure 27
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 Intel Pentium 4 Processor-M
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.
