TIMING SPECIFICATION
PCI Clock Specification
Table 5 summarizes the A. C. characteristics for the PCI bus signals as they apply to the S5920. The figures after
Table 5 visually indicate the timing relationships.

Notes:
1. Rise and fall times are specified in terms of the edge rate measured in V/ns. This slew rate is met across the minimum peak-to-peak portion
2. Minimum times are evaluated with 0 pF equivalent load; maximum times are evaluated with 50 pF equivalent load.
3. For purposes of Active/Float timing measurements, the Hi-Z or 'off" state is defined to be when the total current delivered through the compo-
4. See the timing measurement conditions in Figure 3.
