General Description

The MAX3785 6.25Gbps equalizer operates from a single 1.8V supply and compensates for transmission medium losses encountered with FR-4 transmission lines. Optimized for low-voltage, high-density, DC-coupled interconnections between the line card and switch card, the MAX3785 enables a system upgrade path while maintaining a legacy rate of 2.5Gbps to 3.125Gbps. Roughly the size of two 0603 passive components, the MAX3785 easily provides placement and routing flexibility.
