FBDIMM SPECIFICATION: HIGH SPEED DIFFERENTIAL PTP LINK AT 1.5 V |
JESD8-18A | Mar 2008 |
This specification defines the high-speed differential point-to-point signaling link for FBDIMM, operating at the buffer supply voltage of 1.5V that is provided at the FBDIMM DIMM connector. This specification also applies to FBDIMM host chips which may operate with a different supply voltage. The link consists of a transmitter and a receiver and the interconnect in between them. The transmitter sends serialized bits into a lane and the receiver accepts the electrical signals of the serialized bits and transforms them into a serialized bit-stream. The first generation FBDIMM link is being specified to operate from 3.2 to 4.8 Gb/s. The specifications are defined for three distinct bit-rates of operation: 3.2 Gb/s, 4.0 Gb/s and 4.8 Gb/s.

FBDIMM STANDARD: DDR2 SDRAM FULLY BUFFERED DIMM (FBDIMM) DESIGN STANDARD |
JESD205 | Mar 2007 |
This standard defines the electrical and mechanical requirements for 240-pin, PC2-4200/PC2-5300/PC2-6400, 72 bit-wide, Fully Buffered Double Data Rate Synchronous DRAM Dual In-Line Memory Modules (DDR2 SDRAM FB-DIMMs).These SDRAM FB-DIMMs are intended for use as main memory when installed in systems such as servers and workstations. PC2-4200/PC2-5300/PC2-6400 refers to the DIMM naming convention in which PC2-4200/PC2-5300/PC2-6400 indicates a 240-pin DDR2 DIMM running at 266/333/400 MHz DRAM clock speed and offering 4266/5333/6400 MB/s bandwidth.
