Revision 3.0
Electrical Specifications
8.3.5
The SC2200 is compliant with PCI Bus Rev. 2.1 specifications. Relevant information from the PCI Bus specifications is pro-
vided below.
All parameters in Table 8-17 are not 100% tested. The parameters in this table are further described in Figure 8-13.

Refer to the V/I curves in Figure 8-13. This specification does not apply to PCICLK0, PCICLK1, and PCIRST# which
are system outputs.
Maximum current requirements are met when drivers pull beyond the first step voltage. Equations which define these
maximum values (A and B) are provided with relevant diagrams in Figure 8-13. These maximum values are guaranteed
by design.
Rise slew rate does not apply to open-drain outputs. This parameter is interpreted as the cumulative edge rate across
the specified range, according to the test circuit in Figure 8-12.
