DDR5 REGISTERING CLOCK DRIVER (RCD) IP - (DDR5RCD01)

Overview

The DDR5RCD01 is a registering clock driver used on DDR5 RDIMMs and LRDIMMs. Its primary function is to buffer the Command/Address (CA) bus, chip selects, and clock between the host controller and the DRAMs. It also creates a BCOM bus which controls the data buffers for LRDIMMs.
