| 9M Network Search Engine (NSE) with 2 Port AMCC XSC Interface Advanced Information IDT75K62213 To request the full datasheet, please contact your local IDT Sales Representative or call 1-831-754-4555 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 2 Port 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 multiple XSC requirements of the nP7510. The 75K62213 is compliant with the XSC specification and the device may be optionally expanded up to eight devices deep providing 2 million entries of 32-bit width.
