Notes:
1. Note that the symbols used for timing specifications herein 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. 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.
5. 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 15, “Clocking.”
6. The setup and hold time is with respect to the rising edge of HRESET.
7. 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.
8. The reset assertion timing requirement for HRESET is 100
μs.
9. Guaranteed by characterization.
10.Guaranteed by design.
