CAB4AZNRR

Overview

The CAB4AZNRR is a DDR4 registered clock driver (RCD) designed for DDR4 memory subsystems. It integrates a 32-bit 1:2 command/address/control buffer and a 1:4 differential clock buffer. Operating at 1.2V, the device supports DDR4-2400 speeds with a maximum data rate of 2.4Gbps. It features an internal PLL, configurable driver strength, programmable latency, and address mirroring. The component is housed in a 253-pin NFBGA package and operates within a temperature range of -40°C to +95°C.

Feature Summary

• DDR4 RCD01 JEDEC Compliant
• 32-bit 1-to-2 Register Outputs
• 1-to-4 Differential Clock Buffer
• 1.2V Operation

Applications

• DDR4 Registered DIMM (RDIMM)
