Description

   IDT provides proven, industry-leading network search engines (NSEs) and a comprehensive suite of software that enable and accelerate the intelligent processing of network services in communications equipment. As a part of the complete IDT classification subsystem that includes content inspection engines, the IDT family of NSEs delivers highperformance, feature-rich, easy-to-use, integrated search accelerators.

   The IDT 75K62100 NSE is a high performance pipelined low-power, synchronous full-ternary 128K x 72 entry device. Each entry location in the NSE has both a Data entry and an associated Mask entry. The NSE devices integrate content addressable memory (CAM) technology with high-performance logic. They can perform Lookup and Learn NSE operations plus Read, Write, Burst Write, and Dual Write maintenance operations.

   The IDT 75K62100 NSE device has a bi-directional bus that is a multiplexed address and data bus that can support 100 million sustained searches per second. This device provides array segments which can be configured to enable multiple width lookups from 36 to 576 bits wide. The IDT 75K62100 requires a 1.2-volt VDD supply and a 2.5-volt VDDQ supply. This NSE device provides the user with flexibility and control in determining the device power. Only the array segments that will be used for a specific NSE operation are powered up while the unused segments are not.

   The IDT 75K62100 utilizes the latest high-performance 1.2V CMOS processing technology and is packaged in a JEDEC Standard, thermally enhanced, low profile Ball Grid Array. The IDT 372 BGA package provides increased heat transfer for thermally challenged systems. The 372 BGA footprint is backwards compatible with the IDT 64K x 72 Entry (75P52100) and 32K x 72 Entry (75P42100) NSE devices.
