10/7/2004 - Extending its technology leadership in precision timing and high speed electronic components, Inphi Corporation (www.inphi-corp.com) announced that it has delivered to customers the industry's first Register and Phase Lock Loop (PLL) for Registered DIMMs (RDIMM) operating at 667 and 800 Mbps using Double Data Rate2 (DDR2) technology. Both the The PLL and register are part of the company's ExacTik Family of precision timing devices.
The Inphi products, CU877, SSTUA32866 and the SSTUA32868 support existing standards of DDR2-400 and DDR2-533 as well as new standards for server memory operating at DDR2667 and DDR2-800. Utilizing its expertise in high-frequency and analog chip design enabled Inphi to achieve this substantial market lead in the development of next generation higher data rate DDR2 logic for RDIMMs.
"This announcement exemplifies Inphi's continued drive to deliver cutting-edge solutions that speed development and adoption of DDR2 applications," commented Desi Rhoden, chairman of the JEDEC Memory Committee and executive vice president of Inphi Corporation. "By working closely with JEDEC and our customers, we have again been able to set the bar in terms of precision performance."
The Inphi SSTUA32866 and SSTUA32868 1.8-V Configurable Registered Buffer with Parity for DDR2 RDIMM applications meets or exceeds all electrical specifications adopted by JEDEC. In addition to increasing the application frequency from 270 MHz to 410 MHz, the devices also make significant improvements in AC switching characteristics. For example, the specification for propagation delay was reduced from 2.35 nano-seconds for DDR2-533to 1.8 nano-seconds.
Propagation delay is a critical parameter for servers since the move to faster data rates shortens the clock period and hence, the time memory devices have for reading and writing data. The propagation delay through the register device consumes the largest portion of this clock period.
The Inphi CUA877 PLL Clock Driver for registered DDR2 DIMM applications meets or exceeds all of the electrical specifications adopted by JEDEC. In addition to increasing the application frequency from 270 MHz to 410 MHz, the devices also make considerable improvements in terms of lowering jitter, duty cycle distortion, dynamic phase offsets and skew.
Price and Availability
The Inphi CUA877, SSTUA32866 and SSTUA32868 are all currently shipping. The parts are priced beginning at $3.10 for quantities of 100,000 units. For more information on these products send an email to: firstname.lastname@example.org.
