Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm package type and tape/reel specifications. Confirm current product status as listings may indicate end-of-life or limited availability. Ensure compatibility with target DDR4 memory speeds and server platform requirements before procurement.

Selection Notes

Select this component for high-reliability server memory designs requiring Gen 2.5 DDR4 support. Verify that the 253-ball FCCSP footprint matches the PCB layout constraints. Ensure the design utilizes the 1.2V supply rail and accommodates the required thermal dissipation for the specified operating temperature range.

Part Context

This part belongs to the 4RCD0232K family of registered clock drivers from Renesas Electronics. These components are critical timing elements in high-performance computing systems, ensuring signal integrity for DDR4 memory interfaces in data center environments.

Replacement Considerations

Check for updated revisions within the 4RCD0232K series. Verify pinout compatibility if substituting with other RCD models. Consult official lifecycle notices for potential obsolescence risks associated with older packaging variants.
