Linear Equalizers

High-performance linear equalizer product line for use in high speed copper connections such as, but not limited to Ethernet, InfiniBand and Fibre Channel. The product line supports NRZ and PAM-4 multi-level signal connectivity and builds upon MACOM’s long-standing expertise in equalizers for broadcast video applications. The product line can support up to 112Gbps per lane data rates for 50 Gbps to 800 Gbps copper cable assemblies. 

In addition to copper cables, the linear equalizer can be used for wired backplane and on-board applications. Adding linear equalization to a passive copper cable can enable the same copper cable to carry higher data rates for longer distances. MACOM’s new linear equalizer product line can extend a typical copper cable’s performance to 7.5 meters at 56 Gbps and 5 meters at 112 Gbps data rates. Hyperscale cloud and Internet Service Providers may now consider active copper cables as an alternative to passive copper cables or active optical cables.     

Key benefits include low power consumption from a single 3.3V supply, low latency, hardware and microcontroller management modes. The products are suitable for small SFP, QSFP, QSFP-DD and OSFP connector form factors.
