Figure 2-17: PCI Arbiter
One of the PCI masters on the ITE IT8209 PCI arbiter is connected to the Intel® ICH9DO
Southbridge. The remaining two are connected to the PCI edge connector to facilitate PCI
expansion on the backplane. Some of the features of the ITE IT8209 PCI arbiter are listed
below:
Extended PCI Arbiter
Input PCI Clock
Clock Buffer
2.7.3 PCI Interface Edge connector
The PCI interface edge connector is connected to two PCI Masters on the ICH9DO
Southbridge and to two PCI masters on the ITE IT8209 PCI arbiter. The PCI bus edge
connector on the PCIE-Q350 is interfaced to the PCI bus on the backplane thereby
connecting the PCI backplane expansion boards to the Intel® ICH9DO Southbridge. The
PCI bus edge connector is shown in Figure 2-18 .

The PCI is interfaced to four standard PCI expansion cards a compatible PICMG 1.3
backplane.
