Press Release Summary:
Intended for registered dual in-line memory modules (RDIMMs), SN74SSQE32882 phase locked loop (PLL) integrated DDR3 register enables system stability through constant clock and output delay over voltage and temperature variation. Supporting parity features, 28-56 bit registered buffer operates at 1.5 V VDD, supports data rates of 800-1,333 Mbps, and can support up to 72 DRAMs on one module. It features CKE power down, control mode register, and 300-670 MHz operating frequency.

TI Announces Industry's First Full Production Release of DDR3 Register
Device delivers high stability for memory modules
DALLAS (April 15, 2008) - Texas Instruments (TI) (NYSE: TXN) today announced the industry's first full production release of a phase locked loop (PLL) integrated DDR3 register for registered dual in-line memory modules (RDIMMs). This device enables system stability through constant clock and output delay over voltage and temperature variation. The single-chip quad rank support saves overall board space and reduces power consumption in servers, work stations and storage equipment. (See http://www.ti.com/sn74ssqe32882-pr.)
The SN74SSQE32882 28-bit to 56-bit registered buffer operates at 1.5 V VDD and supports parity features to ensure reliability. It provides flexibility by supporting high data rates of 800 Mbps to 1,333 Mbps and can support up to 72 DRAMs on one module.
Other key features include the following:
o CKE power down
o Control mode register
o Output driver strength control
o Operating frequency: 300 to 670 MHz
The SN74SSQE32882 exceeds the requirements for stability over temperature and voltage defined by the Joint Electron Device Engineering Council. This ensures reliability in high-performance server systems. "TI is pleased to offer the first qualified and fully compatible DDR3 register to the market," said Nick Hassan, general manager of TI's Interface and Clock products group. "By working with leading industry partners, TI has designed the SN74SSQE32882 to exceed the stringent performance and stability requirements of DDR3 systems."
DDR solutions ease design
TI's DDR3 register adds to a complete portfolio of leading DDR2 registers and PLL devices such as the CDCUA877 and SN74SSTUB32866. In addition, the TPS51116 and TPS51100 DC/DC controllers significantly reduce the number of external components that support all the power management requirements for DDR systems.
The SN74SSQE32882 is available now in a 176-ball MicroStar(TM) BGA package. Suggested resale pricing in 1,000-unit quantities is $5.90.
