Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

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 6.25Gbps, the MAX3785 compensates for 30in of FR4 board material. The MAX3785 is coding independent,functioning equally well for 8b/10b or scrambled signals. The MAX3785 features DC-coupled current-mode logic (CML) data inputs and outputs. It is packaged in a tiny 1.5mm × 1.5mm chip-scale package (USCP™) and a 6-pin TDFN package.
