Product Description
M88DR5RCD01 is a Gen1 DDR5 Registering Clock Driver (RCD) for driving address and control nets on DDR5 RDIMM and LRDIMM applications. The RCD01 is fully compliant with the JEDEC DDR5RCD01 specification and can be used as a central buffer on an RDIMM or LRDIMM to enable higher capacity for the memory systems.
Notes: Here shows the application of RCD on the DDR5 RDIMM as an example.
