PCI AC Electrical Specifications
This section describes the general AC timing parameters of the PCI bus. Note that the SYSCLK signal is
used as the PCI input clock. Table 56 provides the PCI AC timing specifications at 66 MHz.
Figure 41 provides the AC test load for PCI.

Notes:
1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tPCIVKH symbolizes PCI timing
(PC) with respect to the time the input signals (I) reach the valid state (V) relative to the SYSCLK clock, tSYS, reference (K)
going to the high (H) state or setup time. Also, tPCRHFV symbolizes PCI timing (PC) with respect to the time hard reset (R)
went high (H) relative to the frame signal (F) going to the valid (V) state.
2. See the timing measurement conditions in the PCI 2.2 Local Bus Specifications.
3. All PCI signals are measured from OVDD/2 of the rising edge of PCI_SYNC_IN to 0.4 × OVDD of the signal in question for
3.3-V PCI signaling levels.
4. 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.
5. Input timings are measured at the pin.
6. The timing parameter tSYS indicates the minimum and maximum CLK cycle times for the various specified frequencies. The
system clock period must be kept within the minimum and maximum defined ranges. For values see Section 19, “Clocking.”
7. The setup and hold time is with respect to the rising edge of HRESET.
8. The timing parameter tPCRHFV is a minimum of 10 clocks rather than the minimum of 5 clocks in the PCI 2.2 Local Bus
Specifications.
9. The reset assertion timing requirement for HRESET is 100
μs.
