MAX3983UGK+D

Sensor And Detector Interfaces Overview

The MAX3983UGK+D is a quad copper-cable signal conditioner operating 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.

Sensor And Detector Interfaces Procurement Notes

Verify the component authenticity by checking the manufacturer's marking against official datasheet specifications. Confirm the package type matches the 68-pin QFN format. Ensure the temperature range aligns with industrial requirements. Cross-reference the part number suffixes to ensure compatibility with your system design. Always refer to the latest documentation from Analog Devices for any updates.

Sensor And Detector Interfaces Selection Notes

Consider the specific data rate requirements when selecting this component. Evaluate the cable length and gauge to determine if the built-in equalization is sufficient. Assess the power consumption constraints to ensure the 1.6W total power fits within your thermal budget. Verify the interface compatibility with your host system's CML inputs and outputs. Review the environmental conditions to confirm the operating temperature range meets your application needs.
