Data buffer from Renesas is JEDEC-compliant for cloud services

A high-speed, low-power DDR5 data buffer by Renesas is for data centre, server and high-performance workstation applications.

The JEDEC-compliant DDR5 data buffer 5DB0148 enables “significantly higher” speeds and lower latency for load-reduced dual inline memory modules (LRDIMMs) for memory- and bandwidth-intensive applications such as real-time analytics, machine learning, high performance computing (HPC) and AI, and other memory and bandwidth-hungry applications. The first generation of DDR5 LRDIMMs based on Renesas components enable a bandwidth increase of more than 35 per cent over DDR4 LRDIMMs operating at 3200million transfers per second.

The DDR5 data buffer maximises channel eye opening for systems that are heavily loaded with a combination of capacitive load reduction, data alignment, and signal recovery techniques. Server motherboards with a large number of memory channels and slots and complex routing topologies are able to run at maximum speed, even when fully populated with high-density memory, says Renesas.

Improvements in the DDR5 modules allow for lower power supply voltages (1.1V compared with 1.2V in DDR4), on-DIMM voltage regulation, and advanced control plane architectures with the use of the SPD hub and control bus communications such as I3C.

The DDR5 data buffer 5DB0148 is optimised to work seamlessly with the other DDR5 Renesas components on an LRDIMM memory module, including the power management IC P8900, the registered clock driver 5RCD0148, the SPD hub SPD5118, and the temperature sensor TS5111.

The DDR5 data buffer 5DB0148 is sampling to qualified customers.
