Switching Characteristics and Requirements
Clock Switching Requirements
Table 15 shows typical and maximum power dissipation of the
AMD-762 system controller during normal and reduced power
states. The measurements are taken with the V
The AMD-762 system controller signal switching characteristics
and requirements are presented in Tables 16 through 27. All
signal timings are based on the following conditions:
n The target signals are input or output signals that are
n Measurements are taken from the time the reference signal
n Parameters are within the range of those listed in
Table 16 contains the switching characteristics of the SYSCLK
input to the AMD-762 system controller for 100-MHz processor
bus operation. These timings are all measured with respect to
the volt age levels indicated by Figure 12 on page 54. Clock
skew requirements are shown in Figure 14 on page 56. Table 17
on page 55 conta ins the switch ing ch a ra c t e r istics of the
AGPCLK inp u t for 66-MHz PCI bus operation. Table 18 on
page 55 contains the switching characteristics of the PCICLK
input for 33-MHz PCI bus ope ration. These timings are all
