Product Brief IDT75K52134 IDT75K62134 4.5M and 9M Network Search Engine (NSE) with QDR™ Interface To request the full datasheet, please contact your local IDT Sales Representative or call 1-831-754-4555 Introduction Device Description Evolving network speeds require critical functions such as forwarding and classification to migrate towards dedicated hardware devices. The Network Search Engine (NSE) based on IDT's CAM (Content Addressable Memory) technology accelerates search functions required for applications such as Access Control Lists (ACL), Flow Caching and Forwarding. The NSE with a single QDR™ (Quad Data Rate) interface is intended to work with any NPU having a QDR™ look aside interface. Multiple devices including the QDR™ NSE can be connected to the same QDR™ interface. Each QDR™ NSE device may be point-to-point expanded up to eight NSE devices.
