NETWORK SEARCH ENGINE 32K x 72 Entries Datasheet Brief 75N43102 Device Description IDT provides proven, industry-leading network search engines (NSEs) that enable and accelerate the intelligent processing of network services in communications equipment. As a part of the complete IDT classificationsubsystemthatincludescontentinspectionengines,theIDT family of NSEs delivers high-performance, feature-rich, easy-to-use, integrated search accelerators. The IDT 75N43102 is ideally suited for cost-sensitive applications in the enterprise and access markets. It is a full-ternary 32K x 72 entry device where each entry location in the NSE has both a Data entry and an associated Mask entry. The NSE devices integrate content addres- sable memory (CAM) technology with high-performance logic. The devicecanperformLookupoperationsplusReadandWritemaintenance operations. The IDT 75N43102 NSE device has a bi-directional bus that is a multiplexedaddressanddatabusthatcansupport62.5millionsustained searches per second. This device can be configured to enable multiple width lookups from 72 to 288 bits wide. The IDT 75N43102 requires a 1.5-volt VDD1 supply and a 2.5-volt VDD2 supply. The IDT 75N43102 NSE utilizes the latest high-performance 1.5V CMOS processing technology and is packaged in a JEDEC Standard, 256 pin low profile Ball Grid Array.

In solutions requiring data searching such as routers, a system configuration as shown in Figure 1.0 may be realized. In this compatible configuration, the NSE interfaces directly to an ASIC/ FPGA for lookups and routes an Index directly back to the ASIC/ FPGA. Control of the associated handshake signals is provided by the NSEs for this configuration. ASIC or FPGA |
