Quad Channel 112Gbps PAM4 Linear Equalizer Offer Ultra-Low Latency for Active Copper Cable and Backplane Applications

CooperEdge GN8112

Semtech Corporation has announced the launch of the new CopperEdge product portfolio GN8112 which is a quad channel 112Gbps PAM4 linear equalizer designed for use in next generation 400G (4x100G) and 800G (8x100G) data center interconnects using copper cable and backplane interconnects. 

The CopperEdge GN8112 enable low cost, manufacturable ACCs that can deliver reaches of up to five meters over a copper twinaxial (Twinax) cable assembly. This reach extension enables ACCs to service the large volume 400G and 800G data center interconnects while offering ultra-low power (<0.75 Watt per 400G) and ultra-low latency (<10ps).

Key Features of CopperEdge GN8112

  • Quad 56GBaud (112Gbps) linear equalizer
  • Low power consumption
  • Operates from a single 3.3V power supply with an integrated POR
  • Low latency
  • Linear PAM4 programmable equalizer optimized for 56GBaud copper link with up to 15dB equalization
  • Enables a transparent ACC solution meeting all IEEE 400GBASE-CR4 Auto-Negotiation and Link Training requirements

The CopperEdge GN8112 is now available for sampling. Semtech also offers ACC Reference Design Kits (RDKs) for the GN8112 to enable rapid adoption of Semtech’s solution.
