M88DR5RCD02 (Gen2 DDR5 RCD)

Product Description

M88DR5RCD02 is a Gen2 DDR5 Registering Clock Driver (RCD02) with a maximum data rate of 5600MT/s. Compliant with the latest JEDEC DDR5RCD02 specification, the RCD02 contains two separate channels and supports 1.1V VDD supply. It is designed for use on DDR5 RDIMMs to enable memory systems with higher capacity and lower power consumption for data-intensive applications such as high-performance computing (HPC) and artificial intelligence (AI).
