Clock Conguration Modes
7.3
PCI Agent Mode
Table 18 and Table 19 show congurations for PCI agent mode. The frequencies listed are for the purpose
of illustration only. Users must select a mode and input bus frequency so that the resulting conguration
does not exceed the frequency rating of the user’s device. In addition, note the following:
NOTE: PCI_MODCK
In PCI mode only, PCI_MODCK comes from the LGPL5 pin and
MODCK_H[0–3] comes from {LGPL0, LGPL1, LGPL2, LGPL3}.
NOTE: Tval (Output Hold)
The minimum Tval = 2 when PCI_MODCK = 1, and the minimum
Tval = 1 when PCI_MODCK = 0. Therefore, designers should use clock
congurations that t this condition to achieve PCI-compliant AC timing.
1 “Low” values are the minimum allowable frequencies for a given clock mode. The minimum bus frequency guarantees the
required minimum CPU operating frequency. Minimum CPU frequency is determined by the clock mode.
For modes with a CPU multiplication factor
≤ 3, the minimum CPU frequency is 166 MHz. The minimum CPM frequency
is 133 MHz.
For modes with a CPU multiplication factor
≥ 3.5, the minimum CPU frequency is 250 MHz. The minimum CPM frequency
is as shown in the table.
“High” values are for the purpose of illustration only. Users must select a mode and input bus frequency so that the resulting
conguration does not exceed the frequency rating of the user’s device.
2 As Table 14 shows, PCI_MODCK determines the PCI clock frequency range. Refer to Table 16 for higher congurations.
3 MODCK_H = hard reset conguration word [28–31]. MODCK[1-3] = three hardware conguration pins.
4 60x and local bus frequency. Identical to CLKIN.
5 CPM multiplication factor = CPM clock/bus clock
6 CPU multiplication factor = Core PLL multiplication factor
