See the timing measurement conditions.
Parts compliant to the 3.3 V signaling environment.
REQ# and GNT# are point-to-point signals and have different output valid delay and input setup
times than do bused signals. GNT# has a setup of 10 ns for 33 MHz and 5 ns for 66 MHz; REQ# has
a setup of 12 ns for 33 MHz and 5 ns for 66 MHz.
RST# is asserted and de-asserted asynchronously with respect to CLK.
All PCI outputs must be asynchronously driven to a tri-state value when RST# is active.
Setup time applies only when the device is not driving the pin. Devices cannot drive and receive
signals at the same time.
Timing was tested with a 70-pF capacitor to ground.
For additional information, see the PCI Local Bus Specification, Revision 2.2.
CLK
Clock to output for all bused
signals. This is the PCI_AD[31:0],
PCI_CBE_N [3:0], PCI_PAR,
PCI_FRAME_N, PCI_IRDY_N,
PCI_TRDY_N, PCI_STOP_N,
PCI_DEVSEL_N, PCI_PERR_N,
PCI_SERR_N
Clock to output for all point-to-
point signals. This is the
PCI_GNT_N and PCI_REQ_N(0)
only.
Input setup time for all bused
signals. This is the PCI_AD[31:0],
PCI_CBE_N [3:0], PCI_PAR,
PCI_FRAME_N, PCI_IRDY_N,
PCI_TRDY_N, PCI_STOP_N,
PCI_DEVSEL_N, PCI_PERR_N,
PCI_SERR_N
Input setup time for all point-to-
point signals. This is the
PCI_REQ_N and PCI_GNT_N(0)
only.
Input hold time from clock.
