4DB0226KA3AVG

Overview

The 4DB0226KA3AVG is a DDR4 data buffer manufactured by Renesas Electronics, designed for enterprise-class server applications. It operates with a 1.2V Vdd supply and supports DDR4 speeds of 1600, 1866, 2133, and 2400 MT/s. The component is housed in a 53-pin flip chip CSP package and functions as part of the memory interface solution for Load-Reduced DIMMs (LRDIMMs). Nine buffers are utilized per LRDIMM to manage 72 bits of DDR4 DRAM data.

Feature Summary

• JEDEC-compliant data buffering for Gen 1.5 DDR4 standards
• Optimized specifically for enterprise-class server LRDIMM architectures
• Designed for integration with the 4RCD0124K RCD and TSE2004GB2 temperature sensor

Applications

• Enterprise class server memory modules
• Load-reduced dual in-line memory modules (LRDIMMs)
• Systems utilizing Intel Xeon processor E5-2600 v4 series

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Availability is restricted, and current stock levels may be limited or unavailable through standard distribution channels. Engineers should verify the specific status with authorized suppliers before initiating procurement processes.

Selection Notes

Selection requires compatibility with the 4RCD0124K register clock driver and TSE2004GB2 temperature sensor within an LRDIMM design. The device supports 1.2V operation and is suitable for systems requiring high-capacity memory solutions based on 8Gb DDR4 DRAMs.

Part Context

The 4DB0226KA3AVG belongs to the 4DB0226 series of memory controllers. Originally developed by IDT prior to its acquisition by Renesas Electronics, this component facilitates advanced memory configurations for high-performance computing environments.

Replacement Considerations

The 4DB0232KC is identified as a substitute DDR4 data buffer option.
