“First” PLL integrated DDR3 register for RDIMM

The SN74SSQE32882 is the industry’s first full production release of a phase locked loop (PLL) integrated DDR3 register for registered dual in-line memory modules (RDIMMs). It 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.

The SN74SSQE32882 28-bit to 56-bit registered buffer operates at 1.5V VDD and supports parity features to ensure reliability. It provides flexibility by supporting high data rates of 800Mbps to 1,333Mbps and can support up to 72 DRAMs on one module.

Other key features include CKE power down; control mode register; output driver strength control; and operating frequency: 300MHz to 670MHz. The SN74SSQE32882 exceeds the requirements for stability over temperature and voltage defined by Joint Electron Device Engineering Council. This ensures reliability in high-performance server systems. The DDR3 register exceeds the stringent performance and stability requirements of DDR3 systems.
