IDT75K52134

4.5M and 9M Network Search Engine (NSE) with QDR™ 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 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. NSE Features x x x External Interfaces The following external interfaces are supported by the QDR™ NSE device Single QDR™ NPU interface - QDR™ Clock Frequency up to 250 MHz - Supports QDR™ 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® 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 Dat...
