Inphi Corp. has introduced the INSSTE32882-GS02, a DDR3 configurable integrated register that exceeds JEDEC requirements and adds quad rank support.

The INSSTE32882-GS02 delivers low jitter and tightly controlled propagation delay. The INSSTE32882-GS02 has a typical propagation delay of 0.8nS, which is below the JEDEC proposed specification of 1nS with minimal variation across process, voltage and temperature. In addition, since the INSSTE32882-GS02 meets DDR3-800 to DDR3-1600 rates, it allows memory vendors to use a single register for all four speed grades reducing costs and reducing BOMs.

The INSSTE32882-GS02 also exceeds the Tdynoff specification at all operating data rates. Tdynoff is a critical specification that ensures the server platform will be able to meet its stated operating frequency and density.

Designed for high-performance DDR3 RDIMM server applications, the Inphi SSTE32882-GS02 supports all existing DDR3-800, DDR3-1066, DDR3-1333 and DDR3-1600 standards. The registered buffer offers quad-rank support for improved energy efficiency in server memory, typically the second largest power drain in a server.

The INSSTE32882-GS02 is manufactured in 0.18?s. The configurable registered buffer is available in a 176-ball TFBGA green package.

Shipping today, the device is priced at $5.83 in quantities of 1,000 units.
