Overview
The 5RCD0148HC3AVG8 is a DDR5 Gen 1.0 Server Registered Clock Driver (RCD) manufactured by Renesas Electronics Corporation. It supports data transfer rates up to 4800 MT/s and operates within an input voltage range of 1.04V to 1.16V. The device features two independent channels, each buffering a 7-bit double data rate Command Address (CA) bus with single parity input. It generates two copies of 14-bit single data rate CA outputs and chip-select outputs per channel. Designed for enterprise servers, it utilizes a 240-lead FCCSP package measuring 13.5 x 8.7 x 0.92 mm with a 0.65 mm pitch.
Feature Summary
- Supports DDR5 server speeds up to 4800 MT/s
- Dual-channel architecture with independent operation
- Buffers 7-bit DDR CA inputs to 14-bit SDR CA outputs
- Generates BCOM bus for LRDIMM data buffer control
Applications
- RDIMM modules for enterprise servers
- LRDIMM modules for enterprise servers
- NVDIMM modules for enterprise servers
- RDIMM modules for telecom applications
Procurement Notes
Verify the specific suffix 'AVG8' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with the target DDR5 memory module specifications before procurement. Confirm that the 1.04V - 1.16V supply voltage aligns with the system design requirements.
Selection Notes
Select this component for DDR5 server environments requiring speeds up to 4800 MT/s. It is suitable for RDIMM, LRDIMM, and NVDIMM configurations. Consider the 240-lead FCCSP package dimensions when designing the PCB layout. Verify support for the required number of chip selects and parity bits for the specific memory topology.
Part Context
This device belongs to the 5RCD0148 family of DDR5 Gen 1.0 Server RCDs. It serves as a critical interface between the host controller and DRAMs, buffering command, address, and clock signals. The family includes variants like the 5RCD0148HC2, which shares similar functional characteristics but may differ in specific suffixes or qualification status.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Renesas technical support for qualified alternatives if this specific variant is unavailable.
