Semtech’s CopperEdge GN8112 quad-channel linear equalizer extends copper cable attain as much as 5 meters at 112-Gbps PAM4 information charges. Geared toward 400G (4x100G) an 800G (8x100G) information heart purposes, the machine provides each low energy and low latency for lively copper cable and backplane interconnects.
As information heart interconnects transition to 112-Gbps PAM4 per lane to fulfill larger bandwidth and throughput calls for, passive copper cables solely allow a attain of as much as 1.5 meters. This severely limits the use instances of passive copper cables in information facilities at 112 Gbps and has created a requirement for lively copper cables (ACCs) that reach the copper cable attain to permit for the high-volume switch-to-server connections.
In accordance with Semtech, the GN8112 equalizer allows low price, manufacturable ACCs that may ship a attain of as much as 5 meters over a copper twinaxial cable meeting. This attain extension allows ACCs to service the large-volume 400G and 800G information heart interconnects, whereas providing ultra-low energy (<0.75 Watt per 400G) and ultra-low latency (<10ps). The GN8112 offers programmable equalization of as much as 15 dB.
The GN8112 112-Gbps PAM4 equalizer is now obtainable for sampling. Semtech additionally provides ACC reference design kits for the GN8112.
