M88DDR4RCD02 (Gen2 DDR4 RCD)

Product Description

M88DDR4RCD02 is a 32-bit 1:2 configurable Registering Clock Driver (RCD) with parity check for DDR4 RDIMM and LRDIMM applications. The RCD is compliant with JEDEC DDR4RCD02 specification and supports data rates up to DDR4-2666. It can be used independently as a central buffer on RDIMM or used in conjunction with 9 DDR4 DBs on LRDIMM to provide advanced memory solutions with higher capacity, higher speed, and lower power consumption for server platforms.


Notes: Here shows the application of RCD on the DDR4 RDIMM as an example.
