Description

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.
