DSC - 7042/2 c COMMERCIAL TEMPERATURE RANGE FEATURES: • Advanced Memory Buffer for Fully buffered DIMMs • 3.2 and 4 Gbit/s serial speeds (DDR2-533 and 667 DRAM) • Support for up to eight DIMMs per channel • Repeater Mode for extending FB-DIMM links • Northbound and Southbound single lane fail over and channel error detection • Voltage and Timing margin high-speed I/O test capability • Fully Supports the FB-DIMM configuration register set • Test features supported include: - Integrated thermal sensor and status indicator - Supports MEMBIST, IBIST and Virtual Host mode - Transparent mode and direct access mode for DRAM testing • Complies with JEDEC Architecture and Protocol Specification • Available in 655 ball FCBGA package EXPANDEDFEATURES: • Wide range DDR Timing Control • Superfine adjustment for DDR timing • Wide range of DDR slew rate control • Slew rate controllable independent of output impedance • High speed SMBus in test mode • IBIST IDT PRBS Generator The IDT logo is a registered trademark of Integrated Device Technology, Inc. DESCRIPTION: The fully buffered dual in-line memory module (FB-DIMM) is the next generation memory architecture to meet the growing memory requirement of serversandworkstations.TheIDTAdvancedMemoryBuffer(AMB)chipisthe essential building block located on each FB-DIMM. The IDT AMB receives commands and data from the host controller to control and write/read data to/ fromtheDRAMsontheDIMM.Commandsandwritedataaresentsouthbound from the host controller to AMBs in a daisy chain fashion and interpreted by the target AMB. Status and read data are sent northbound from AMBs to the host controlleralsoinadaisychainfashion,passingthroughnon-targetAMBs.This uniquechannelstructurealleviatesbufferloadingissuescommoninregistered DIMM technology, enabling designers to use a large number of DIMMs within a single system. IDTAMB0480complieswiththelatest JEDECdefinedFB-DIMMArchitecture and Protocol Specification and supports DDR2-533 and DDR2-667 DRAM. It also enables serial data transfer at 3.2 and 4.0Gbps. The IDTAMB0480 supportsservers,workstations,storagedevicesandcommunicationapplications that support the next generation FB-DIMM architecture.
