Semtech’s CopperEdge™:
“As AI workloads drive exponential growth in data center bandwidth requirements, the industry faces critical power and thermal challenges,” said
Semtech’s comprehensive ecosystem approach brings together multiple cable OEM partners, ensuring robust supply chain resilience and consistent product quality at scale. This established partner network enables rapid adoption of CopperEdge technology across diverse AI/ML deployments while maintaining the rigorous performance and reliability standards demanded by hyperscale data centers.
CopperEdge: Enabling the Future of AI Infrastructure
The CopperEdge portfolio supports both current and emerging connectivity standards, with the GN8214 optimized for 112G/channel PAM4 applications (enabling 800G connectivity), while the GN8224 and GN8234 target next-generation 224G/channel PAM4 deployments (supporting1.6T connectivity).
Breakthrough Technical Innovations
- Ultra-low power: Less than 2W per cable end power consumption—90% lower than DSP-basedAECs—enabling denser AI/ML deployments within existing data power envelopes.
- Ultra-low latency: Sub-100ps latency delivers over 100x improvement compared to higher latency DSP-based retimers, critical for distributed AI training.
-
Extended reach performance
- 800G copper cables to 5m.
- 1.6T copper cables to 3m.
- Enhanced PCB trace length for both 112G/channel and 224G/channel designs.
-
Optimized for AI/ML deployments
- Reduced cable diameter improves airflow/cooling in dense compute clusters.
- Seamless compatibility with existing 100G/channel and 200G/channel infrastructure in data centers.
- Simplified deployment versus DSP-based retimers.
The CopperEdge family includes:
- GN8214: 4-channel 112G/channel PAM4 linear equalizer supporting 800G ACC and on-board applications.
- GN8224 / GN8234: Advanced 4-channel 224G/channel PAM4 cable equalizers supporting 1.6T ACC and on-board applications.
