CopperEdge Enhancements for AI Data Centers

Semtech Corporation has unveiled its new CopperEdge family of active copper cable (ACC) and on-board equalization technology, designed to meet the growing demands of AI and machine learning (AI/ML) data centers. This innovative portfolio includes linear equalizer/redriver solutions, specifically the GN8214, GN8224, and GN8234 models. These technologies are optimized for low power consumption, achieving significant energy savings while enhancing connectivity performance.

The CopperEdge solutions provide a notable shift in data center infrastructure by offering longer reach than traditional direct attach copper (DAC) cables. With the ability to support 1.6T ACCs, CopperEdge drastically optimizes bandwidth density while significantly lowering interconnect power use and enabling maximum data throughput within stringent thermal limits.

Brian Bentham, Semtech’s data center market manager, emphasizes that as AI workloads increase data center bandwidth requirements, power and thermal management challenges also escalate. The CopperEdge technology promises to alleviate these issues by providing enhanced signal integrity and reach, all without the complexity and power consumption associated with DSP-based alternatives.

The CopperEdge portfolio is built around collaboration with various cable original equipment manufacturer (OEM) partners. This extensive network ensures robust supply chain capabilities, allowing for the swift integration of CopperEdge technology across a myriad of AI/ML implementations while adhering to the high performance and reliability standards expected by hyperscale data centers.

This innovative product family is designed to accommodate both current and forthcoming connectivity standards. The GN8214 model caters to 112G/channel PAM4 applications, thus facilitating 800G connectivity, while the GN8224 and GN8234 models are tailored for next-generation 224G/channel PAM4 applications, allowing for 1.6T connectivity.

Key features of the CopperEdge technology include:
– Ultra-low power usage, consuming less than 2W per cable end—90% less than DSP-based Active Electrical Cables (AECs), which enables denser AI/ML setups.
– Sub-100 picoseconds latency, offering over 100 times better performance compared to higher latency DSP retimers, crucial for distributed AI training.
– Extended reach, supporting 800G copper cables up to 5 meters and 1.6T cables up to 3 meters.

The reduced cable diameter improves airflow in densely packed compute environments, ensuring seamless integration with existing 100G/channel and 200G/channel infrastructure without the complications seen in DSP-based solutions.
