19-2928; Rev 1; 2/07 EVALUATION KIT AVAILABLE Quad Copper-Cable Signal Conditioner MAX3983 General Description Features The MAX3983 is a quad copper-cable signal conditioner Link Features that operates from 2.5Gbps to 3.2Gbps. It provides com- Span 20m with 24AWG, 15m with 28AWG pensation for 4x copper InfiniBand and 10Gbase-CX4 Span 0.5m of FR4 on Each Host Ethernet links, allowing spans of 20m with 24AWG and 1.6W Total Power with 3.3V Supply 15m with 28AWG. The cable driver section provides four Loopback Function selectable preemphasis levels. The input to the cabledriver compensates for up to 0.5m of FR4 circuit board Cable Driver Features material. The cable receiver section provides additional Selectable Output Preemphasis fixed input equalization while offering selectable preem- FR4 Input Equalization phasis to drive FR4 circuit boards up to 0.5m. Signal Detect for Each ChannelOutput Disable The MAX3983 also features signal detection on all eightinputs and internal loopback that allows for diagnostic Cable Receiver Features testing. It is packaged in a 10mm x 10mm, 68-pin QFN Selectable FR4 Output Preemphasis and operates from 0°C to +85°C.
