M88DDR4RCD01 (Gen1 DDR4 RCD)

Product Description

M88DDR4RCD01 is a 32-bit 1:2 configurable Gen1 DDR4 Registering Clock Driver (RCD) with parity for DDR4 RDIMM and LRDIMM applications. The RCD is compliant with JEDEC DDR4RCD01 specification, supports data rates up to 2400MT/s and VDD supply of 1.2V. By buffering the command, address, control, and clock signals of the memory channel, the chip reduces the load of the memory controller and enhances the signal integrity, thus boosting the capacity and bandwidth of the memory system.


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