19-2928; Rev 1; 2/07 www.DataSheet4U.com KIT ATION EVALU E L B AVAILA Quad Copper-Cable Signal Conditioner General Description Features ♦ Link Features Span 20m with 24AWG, 15m with 28AWG Span 0.5m of FR4 on Each Host 1.6W Total Power with 3.3V Supply Loopback Function ♦ Cable Driver Features Selectable Output Preemphasis FR4 Input Equalization Signal Detect for Each Channel Output Disable ♦ Cable Receiver Features Selectable FR4 Output Preemphasis Cable Input Equalization Signal Detect for Each Channel Output Disable MAX3983 The MAX3983 is a quad copper-cable signal conditioner that operates from 2.5Gbps to 3.2Gbps. It provides compensation for 4x copper InfiniBand and 10Gbase-CX4 Ethernet links, allowing spans of 20m with 24AWG and 15m with 28AWG. The cable driver section provides four selectable preemphasis levels. The input to the cable driver compensates for up to 0.5m of FR4 circuit board material. The cable receiver section provides additional fixed input equalization while offering selectable preemphasis to drive FR4 circuit boards up to 0.5m. The MAX3983 also features signal detection on all eight inputs and internal loopback that allows for diagnostic testing. It is packaged in a 10mm x 10mm, 68-pin QFN and operates from 0°C to +85°C.
