This document 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 applications. The DDR5RCD04 Device ID is DID = 0x0054.

The terms ‘Registering Clock Driver’, ‘RCD’, ‘register’ or ‘device’ are used interchangeably to refer to this device in the remainder of this specification.

The purpose is to provide a standard for the DDR5RCD04 (see Note) logic device, for uniformity, multiplicity of sources, elimination of confusion, ease of device specification, and ease of use. DDR5RCD04 is backwards compatible with DDR5RCD03, DDR5RCD02 and DDR5RCD01.

The designation DDR5RCD04 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.
