Inphi Unveils 800 Mbps DDR2 Registered Buffer with Parity Checking

4/13/2005 - Leveraging its expertise in creating and producing the world's highest performing, fastest precision timing devices, Inphi Corporation ( introduced the world's first Double Data Rate (DDR2) Configurable Registered Buffer with Parity Checking operating at 800 Mbps. A member of the Inphi ExacTik Family of industry-leading precision timing devices, the new product complements the company's DDR2 Registered Buffers with Parity Checking operating at 400, 533, 667 and 800 Mbps.

The Inphi product, SSTUB32866supports all existing standards of DDR2-400 and DDR2-533 as well as standards for server memory operating at DDR2-667 and DDR2-800 rates. The new registered buffer allows customers to immediately incorporate the world's most advanced timing devices into their high performance workstations, middle and high performance servers, and high reliability systems, while capitalizing on higher data rate DDR2 technology.

"This new product highlights Inphi's commitment to working closely with JEDEC and our customers, to rapidly integrating newly-defined technology, and to leveraging our technology and manufacturing expertise to deliver the world's highest precision solutions," said Desi Rhoden, chairman of the JEDEC Memory Committee and executive vice president of Inphi Corporation. "This product further extend Inphi's market lead, making Inphi the world's only logic vendor to delivers all five registers for DDR2 operating at 400, 533, 667 and 800 Mbps using DDR2 technology."

The Inphi INSSTUB32866 configurable 25-bit 1:1 or 14-bit 1:2 register exceeds all JESD82-10 performance specifications for DDR2-400 and DDR2-533 rates and all future performance specifications for DDR2-667, DDR2-800 rates. The part is available in normal or standard 96 Ball LFBGA leaded, lead-free and .green. (lead and halogen-free) packages.

The new registered buffer is designed for nominal 1.8V power supply operation. It supports DDR2 Registered DIMM (RDIMM) module E, F, G, H, J, N and Complies with DDR2 SDRAM Over/Undershoot specification as defined in JESD79-2.

A unique feature of the INSSTUB32866 exhibits the lowest propagation delay in the industry which gives module manufacturers the highest margin in production. In addition, the INSSTUB32866 meets a much tighter minimum and maximum delay window. This allows memory vendors to use a single register for all four speed grades reducing costs and reducing the bill of materials. Up to now a memory module manufacturer would need to use up to three different registers to perform the same function as the INSSTUB32866.

The Inphi INSSTUB32866 is currently shipping in production quantities with pricing starting at $3.63 in quantities of 10,000 units. For more information email:
