Overview

  • Single +3.3V Operation
  • Typical Power Dissipation = 125mW at +3.3V
  • Data Rates Up to 3.2Gbps
  • Equalizer Automatically Adjusts for Different Cable Lengths
  • 0dB to 30dB Equalization at 1.6GHz (3.2Gbps)
  • Loss-of-Signal (LOS-bar) Indicator
  • Cable Integrity Monitor (CIM)
  • On-Chip Input and Output Terminations
  • Low External Component Count
  • Operating Temperature Range = 0°C to +85°C
  • ESD Protection on Inputs and Outputs

The MAX3801 is a +3.3V adaptive cable equalizer designed for coaxial and twin-axial cable point-to-point communications applications. The equalizer includes differential CML data inputs and outputs, a loss-of-signal (active-low LOS) output, and a cable integrity monitor (CIM) output.

The adaptive cable equalizer is capable of equalizing differential or single-ended signals at data rates up to 3.2Gbps. It automatically adjusts to attenuation caused by skin-effect losses of up to 30dB at 1.6GHz. The equalizer effectively extends the usable length of copper cable in high-frequency interconnect applications.

The MAX3801 is available in a 24-pin QFN package with exposed pad and consumes only 125mW at +3.3V.
