DDR5 RDIMM
M88DR5RCD01 (Gen1 DDR5 RCD)
M88DR5RCD01 is a JEDEC-compliant Gen1 DDR5 Registering Clock Driver (RCD), supporting data rates up to 4800 MT/s and VDD supply of 1.1V. It is a two-channel RCD designed for driving and buffering the Command/Address (CA) bus, Chip Selects, and clock between the host controller and the DDR5 SDRAMs. The RCD can be used independently as a central buffer on an RDIMM or used in conjunction with Gen1 DDR5 data buffers (DBs) on an LRDIMM to enable higher capacity and lower power consumption for memory systems.
The left image shows the application of RCD01 on the DDR5 RDIMM as an example.
