Introduction

As part of the IDT IP Co-Processor product family, IDT delivers high performance, feature-rich, easy-to-use, Network Search Engine (NSE) products. Using CAM (Content Addressable Memory) technology, IDT NSE products accelerate search functions for Access Control Lists (ACL), Flow Caching, and forwarding to improve performance in next generation networking equipment.

Device Description

The NSE Quad XSC interface is intended to work with any AMCC NPU with an external search co-processor interface (XSC). It will operate with multiple NPUs such as the nP3400 and nP7250, or can be used to satisfy the four XSC requirements of the nP7510. The 75K52413 is compliant with the XSC specification and the device may be optionally expanded up to eight devices deep providing 1 million entries of 32-bit width.
