Notes:
1.
See the timing measurement conditions in; Figure 7, “Output Timing Measurement Waveforms” on
page 69.
2.
See Figure 16, “PCI/PCI-X TOV(max) Rising Edge AC Test Load” on page 73, Figure 17, “PCI/PCI-X
TOV(max) Falling Edge AC Test Load” on page 74, and Figure 18, “PCI/PCI-X TOV(min) AC Test
Load” on page 74.
3.
Setup time for point-to-point signals applies to REQ# and GNT# only. All other signals are bused.
4.
See the timing measurement conditions in Figure 8, “Input Timing Measurement Waveforms” on
page 70.
5.
RST# is asserted and deasserted asynchronously with respect to CLK.
6.
All output drivers must be floated when RST# is active.
7.
For purposes of Active/Float timing measurements, the HI-Z or ‘off’ state is defined to be when the
total current delivered through the component pin is less than or equal to the leakage current
specification.
8.
Setup time applies only when the device is not driving the pin. Devices cannot drive and receive
signals at the same time.
