| 4.5M and 9M Network Search Engine (NSE) with QDRTM Interface Product Brief IDT75K52134 IDT75K62134 To request the full datasheet, please contact your local IDT Sales Representative or call 1-831-754-4555 Introduction 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. Device Description The NSE with a single QDRTM (Quad Data Rate) interface is intended to work with any NPU having a QDRTM look aside interface. Multiple devices including the QDRTM NSE can be connected to the same QDRTM interface. Each QDRTM NSE device may be point-to-point expanded up to eight NSE devices. NSE Features x x x External Interfaces The following external interfaces are supported by the QDRTM NSE device Single QDRTM NPU interface - QDRTM Clock Frequency up to 250 MHz - Supports QDRTM burst of 2 - Echo clocks supported (CQ, CQ) x Point-to-Point Cascading Interface - Up to eight NSEs can be cascaded using this scheme x Associated Data SRAM with standard ZBT(R) Interface x Boundary Scan JTAG Interface (IEEE 1149.1) x x x x x x x x x x x x x x 128K x 72 (9M) or 64K x 72 (4.5M) Data and Mask cells Full Ternary Content Addressable Memory Advanced Database Management - Selectable Databases - Programmable Width per Database - Lookup widths from 32 to 576 bits - Only the selected Database is powered Lookup Instructions - Standard Lookup - Multi-Hit Lookup - Multi-Database Lookup - Re-Issue Multi-Database Lookup Maintenance Features - Aging - Multi Hit Invalidate - Learn per Database Multi-Context support Pool of (72-bit) Global Mask Registers (shared across contexts) In-Band Control and Management Assoicated Data SRAM is supported through a glue-less ZBT(R) interface Lowest Power per Application Synchronous Pipeline Operation Boundary Scan JTAG Interface 1.2V Core Supply 1.5V HSTL I/O Supply 2.5V I/O Supply for ZBT(R) Associated Data SRAM 35mm x 35mm BGA Package Figure 1.0 QDRTM NSE External Interfaces QDR Read Control Logic 256K x 36 Full Ternary Content Addressable Memory Cascade Interface QDR Write Control Logic ZBT Interface JTAG Interface 6070 drw04aa JANUARY 2003 1 (c) 2002 Integrated Device Technology, Inc.
