JEDEC規格 JESD 82-531, 2024: DDR5 Registering Clock Driver Definition
Description
This standard defines standard specifications of DC interface parameters, switching parameters, and test loading for definition of the DDR5 Registering Clock Driver (RCD) with parity for driving address and control nets on DDR5 RDIMM and LRDIMM applications. The DDR5RCD03 Device ID is DID = 0x0053.
The terms ‘Registering Clock Driver’, ‘RCD’, ‘register’, or ‘device’ are used interchangeably to refer to this device in the remainder of this documernt.
The purpose is to provide a standard for the DDR5RCD03 (see Note) logic device, for uniformity, multiplicity of sources, elimination of confusion, ease of device specification, and ease of use. DDR5RCD03 is backwards compatible with DDR5RCD02 and DDR5RCD01.
NOTE The designation DDR5RCD03 refers to the part designation of a series of commercial logic parts common in the industry. This designation is normally preceded by a series of manufacturer specific characters to make up a complete part designation.
