MAX3982 - SFP Copper-Cable Preemphasis Driver

Description

The MAX3982 is a single-channel, copper-cable preemphasis driver that operates from 1Gbps to 4.25Gbps.

It provides compensation for copper links, such as 4.25Gbps Fibre Channel, allowing spans of up to 15m with 24AWG.

The cable driver provides four selectable preemphasis levels.

Features

  • SFP-compliant loss-of-signal detection with selectable sensitivity and TX_DISABLE. Selectable output swing reduces EMI and power consumption. It is packaged in a 3mm x 3mm, 16-pin thin QFN and operates from 0°C to +85°C temperature range.
  • Drives Up to 15m with 24AWG Cable.
  • Drives Up to 30in of FR4.
  • 0.25W Total Power with +3.3V Supply.
  • Selectable 1600mVP-P or 1200mVP-P Differential Output Swing.
  • Selectable Output Preemphasis.
  • Fixed Input Equa.
