PCI AC Electrical Specifications
This section describes the general AC timing parameters of the PCI bus of the device. Note that the
PCI_CLK or PCI_SYNC_IN signal is used as the PCI input clock depending on whether the device is
configured as a host or agent device.
.
Parameter
Clock to output valid
Output hold from clock
Clock to output high impedance
Input setup to clock
Input hold from clock
Notes:
1. The symbols used for timing specifications follow the pattern of t
inputs and t
(first two letters of functional block)(reference)(state)(signal)(state)
(PC) with respect to the time the input signals (I) reach the valid state (V) relative to the PCI_SYNC_IN clock, t
(K) going to the high (H) state or setup time. Also, t
(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. 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.
