Overview

The GN1185 is a quad-channel laser driver designed to be DC-coupled with directly modulated 25Gbps lasers.

Features

  • Quad-channel DML laser driver chip, designed for co-packaging with 25Gbps to 28Gbps DFB lasers with impedances of 8Ω to 16Ω
  • Power dissipation of GN1185 DML driver = 190mW for four channels (IBIAS = 0mA, IMOD = 0mApp)
  • Interfaces with Semtech CDR IC (GN2104)
  • Maximum programmable bias current (average current through the laser) = 70mA
  • Maximum programmable modulation current = 55mApp (into an 8Ω to 16Ω differential laser load)
  • Eye shaping features—crossing point adjust and input equalization
  • IBIAS/IMOD monitor output
