PCI/PCI-X
15 PCI/PCI-X
This section describes the DC and AC electrical specifications for the PCI/PCI-X bus of the device.
Note that the maximum PCI-X frequency in synchronous mode is 110 MHz.
15.1
PCI/PCI-X DC Electrical Characteristics
This table provides the DC electrical characteristics for the PCI/PCI-X interface.
15.2
PCI/PCI-X AC Electrical Specifications
This section describes the general AC timing parameters of the PCI/PCI-X bus. Note that the clock
reference CLK is represented by SYSCLK when the PCI controller is configured for synchronous mode
and by PCIn_CLK when it is configured for asynchronous mode.
