IDT Introduces Register Supporting DDR3 Memory Modules

IDT (Integrated Device Technology) has announced the industry's fastest JEDEC-compatible integrated register and phase-locked loop for DDR3 registered dual in-line memory modules. The device's integrated PLL supports the industry's widest range of operating clock speeds, from DDR3-800 to DDR3-1600 with a propagation delay of less than 1 nanosecond. Designed for a new generation of high performance servers and workstations, the IDT 74SSTE32882 offers twice the speed of today's DDR2 solution with a 30 percent reduction in power consumption.

In addition, IDT continues to help drive the development of the RDIMM ecosystem by providing the DDR3 industry with a standardized validation platform known as the Register Validation Board. The RVB will allow all members of the DDR3 ecosystem to test, debug, and validate DDR3 Register-DIMMs on a standardized platform. Moreover, the RVB enables the DDR3 community to self-validate the functionality of each of their RDIMM designs, and will further help speed the adoption of DDR3 RDIMMs. The IDT RVB will be available for the DDR3 industry through the JEDEC standards body.

The integration of the register and PLL into a single device enables RDIMM vendors to develop a simplified design and board layout. In addition, the 74SSTE32882 supports an internal PLL feedback loop to reduce trace routing and spread spectrum clocking to reduce EMI. The supply voltage for the 74SSTE32882 is reduced to 1.5V, limiting power consumption and heat generation. These features offer RDIMM vendors important business value because they enable significant cost savings through the reduction of valuable board real estate and the elimination of external components.

In keeping with the IDT objective to support industry standards, the IDT 74SSTE32882 is designed to be fully compatible with the most current JEDEC specification. The guideline set by JEDEC ensures interoperability for all JEDEC compatible DDR3 solutions and will help facilitate the growth of the DDR3 market.
