Intel® IXP45X and Intel® IXP46X Product Line of Network Processors Datasheet

Document Number: 306261-004US

DDRI_RCVENOUT_N

RECEIVE ENABLE OUT must be connected to DDRI_RCVENIN_N signal of the IXP45X/IXP46X

network processors and the propagation delay of the trace length must be matched to the

clock trace plus the average DQ Traces.

DDRI_RCVENIN_N

RECEIVE ENABLE IN provides delay information for enabling the input receivers and must be

connected to the DDRI_RCVENOUT_N signal of the IXP45X/IXP46X network processors.

Description

PCI_AD[31:0]

I/O

PCI Address/Data bus used to transfer address and bidirectional data to and from multiple PCI

devices.

When this interface/signal is enabled and is not being used in a system design, the interface/signal

should be pulled high with a 10-KΩ resistor. When this interface is disabled via the PCI soft fuse

(refer to Expansion Bus Controller chapter of the Intel® IXP45X and Intel® IXP46X Product Line of

Network Processors Developer’s Manual) and is not being used in a system design, this interface/

signal is not required for any connection.

PCI_CBE_N[3:0]

I/O

PCI Command/Byte Enables is used as a command word during PCI address cycles and as byte

enables for data cycles.

When this interface/signal is enabled and is not being used in a system design, the interface/signal

should be pulled high with a 10-KΩ resistor. When this interface is disabled via the PCI soft fuse

(refer to Expansion Bus Controller chapter of the Intel® IXP45X and Intel® IXP46X Product Line of

Network Processors Developer’s Manual) and is not being used in a system design, this interface/

signal is not required for any connection.
