This table shows the PCI AC timing specifications at 33 MHz.
This figure 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 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.
