19-2630; Rev 1; 8/03 6.25Gbps, 1.8V PC Board Equalizer General Description The MAX3785 6.25Gbps equalizer operates from a single 1.8V supply and compensates for transmissionmedium losses encountered with FR4 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. The MAX3785 is comprised of an equalizer, limiting amplifier, and output driver. For data rates of 3.2Gbps and lower, the MAX3785 equalizes signals for spans up to 40in of FR4 board material. For data rates up to 6.
