IDT75K72234 Datasheet (Integrated Device Technology)

IDT75K72234, 18M Network Search Engine (NSE)

The 18M NSE with Dual LA-1 interface is intended to work with NPUs having a Look Aside Interface.

Multiple devices including the 18M Dual LA-1 NSE can be connected to the same LA-1 interface.

Each 18M Dual LA-1 NSE device may be optionally point-to-point expanded up to eight NSE devices.

NSE Featur

18M Network Search Engine (NSE) with Dual LA-1 Interface (QDR™II Interface Compliant) Introduction With the expanding Internet, all levels of the network must become faster.

This requires high-speed packet searches, which are essential for routing, but also necessary for higher-level functions such as Quality of Service (QoS) support and access control.

To meet this need, IDT has developed network search engines that accelerate packet processing at OC-192 data rates and beyond.
