PCI AC Specifications
The AC specifications consist of input requirements and output responses. The input requirements
consist of setup and hold times, pulse widths, and high and low times. Output responses are delays
from clock to signal.
The PCI pins support the basic set of PCI electrical specifications in the PCI Local Bus
Specification, Revision 2.2. See that document for a complete description of the PCI I/O protocol
and pin AC specifications.
