Introduction—Intel®IXP45X and Intel® IXP46X Product Line of Network Processors

1.0Introduction

This design guide provides recommendations for hardware and system designers who are developing with the Intel® IXP45X and Intel® IXP46X Product Line of Network Processors. This document should be used in conjunction with the Intel® IXP45X and Intel® IXP46X Product Line of Network Processors Datasheet and sample schematics provided for the Intel® IXDP465 Development Platform in that platform’s documentation kit.

Design Recommendations are necessary to meet the timing and signal quality specifications.

The guidelines recommended in this document are based on experience and simulation work done at Intel while developing the Intel® IXDP465 Development Platform. These recommendations are subject to change.

Note: This document discusses all features supported on the Intel® IXP465 Network Processor. A subset of these features is supported by certain processors in the IXP45X/ IXP46X product line, such as the Intel® IXP460 or Intel® IXP455 network processors. For details on feature support listed by processor, see the Intel® IXP45X and Intel® IXP46X Product Line of Network Processors Datasheet.
