PCI AC Electrical Specifications
This section describes the general AC timing parameters of the PCI bus of the MPC8309. Note that the
PCI_CLK or PCI_SYNC_IN signal is used as the PCI input clock depending on whether the MPC8309 is
configured as a host or agent device. Table 33 shows the PCI AC timing specifications at 66 MHz.
.
Table 34 shows the PCI AC timing specifications at 33 MHz.

Notes:
1. Note that the symbol VIN, in this case, represents the OVIN symbol referenced in Table 1 and Table 2.
2. Ranges listed do not meet the full range of the DC specifications of the PCI 2.3 Local Bus Specifications.

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 PCI_SYNC_IN 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 2.3 Local Bus Specifications.
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 component pin is less than or equal to the leakage current specification.
4. Input timings are measured at the pin.
