SPD5118 HUB and SERIAL PRESENCE DETECT DEVICE STANDARDRelease Number: Version 1.5.1 |
JESD300-5B.01 | May 2023 |
This standard defines the specifications of interface parameters, signaling protocols, and features for DDR5 Serial Presence Detect EEPROM with Hub function (SPD5 Hub) and integrated Temperature Sensor (TS) as used for memory module applications. The Hub feature allows isolation of a local bus from a Controller host bus. The designation SPD5118 or generic term SPD5 Hub refers to the devices specified by this standard.

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. Patents(): There are known patent issues that are common to all FBDIMM related specifications. See document for link to FBDIMM Patents. Committee(s): JC-16 Free download.
