Circuit Implementations
10.1.1PCI Analog Voltage Filters
The following filter circuit is recommended for the PCI interface. Three separate, identical versions of this circuit should be placed on the system board, one for each VCCAPCI[2:0] pin on the 41110.

Note: Three of these PCI filter circuits must be placed on the system board, one for each of the VCCAPCI[2:0] pins on the 41110.
•Place C as close as possible to package pin.
•R must be placed between VCC15 and L.
•Route VCCPCI[x] and VSS as differential traces.
•VCCPCI[x] and VSS traces must be ground referenced (No VCC15 references).
•Max total board trace length = 1.2”.
•Min trace space to other nets = 30 mils.
