IDT Supports DIMMs with Industry's First Register Validation Board

8/19/2003 - IDTTM (Integrated Device Technology, Inc.; Nasdaq: IDTI), a leading communications IC company, announced its continued support for DDR2 dual in-line memory modules (DIMMs) with the introduction of the industry’s first Register Validation Board (RVB). This test platform enables the analysis of the pre- and post-register address bus of the registered DIMMs to ensure optimum performance. The RVB also allows users for the first time to observe simultaneous switching behavior of the register on a DIMM by way of a quick, easy and accurate test that simulates real-life specific or worst-case address scenarios, enabling the customer to perform robust testing and analysis. In addition to register testing, the RVB has the ability to control additional factors in the test environment, including DIMM voltage, reference voltages, clock speeds and timing relationships between the clocks and address and control signals. The DDR2 RVB was designed by IDT as part of the JEDEC Validation Task Group to ensure that the components deliver performance characteristics that meet the stringent industry requirements dictated by current JEDEC standards.

“IDT leveraged its expertise in DDR2 DIMM technology to enable the development of the Register Validation Board that addresses the current challenges associated with testing these devices,” said Oliver Kiehl, senior staff engineer with Infineon Technologies and chairman of JEDEC's Validation Task Group. “On behalf of the Validation Task Group, I’d like to thank IDT for its significant contribution to this project.”

“The introduction of the DDR2 DIMM Register Validation Board is a significant industry milestone,” said Kevin Walsh, director of strategic marketing for the IDT timing and logic divisions. “In the past, there has not been a common reference test environment for DIMM registers. Previous methods of register testing included actual DIMM testers, bench tests and testing houses. As a result, it was difficult for customers to evaluate registers on a standard platform. The IDT DDR2 Register Validation Board enables an easy and accurate testing environment that is very much like the final application. We are pleased to deliver the first Register Validation Board for DDR2 DIMM support and look forward to the industry’s adoption of this test methodology in the coming years.”

IDT DDR2 DIMM Support Products
IDT is a leading provider of clock management and logic solutions and has leveraged its core competencies to develop a full array of products for the DIMM market. In addition to the new DDR2 RVB, IDT was the first company to introduce a complete chip set of JEDEC-compliant DDR2 DIMM logic components. The IDT DDR2 chip set includes a register that drives the address signals and supports 1:1 (25 bits) and 1:2 (14 bits) configurations, allowing designers to work with a single device for multiple DIMM configurations. The chip set is also comprised of a 1:10 PLL clock driver used for synchronization of input clock signals from the system motherboard to all SDRAMs on the DIMM. The devices target registered DDR2 DIMMs that address the memory needs of growing market areas such as servers, workstations, and communication devices.

Pricing and Availability
The DDR2 RVB is available now and is individually priced at $1,400. CST Inc. is managing the production and distribution of the board for the industry. For additional information, please contact CST Inc. at (972) 241-2662, or visit the company’s Website at
