Product Overview

The MAX3949ETE+T is a 11.3Gbps, low power, AC-coupled laser driver in 16 pin TQFN package. This is 3.3V, multirate, laser diode driver designed for Ethernet, fibre channel & SONET transmission systems at data rates up to 11.3Gbps. It is optimized to drive a differential transmitter optical subassembly (TOSA) with a 25ohm flex circuit. The unique design of output stage enables use of unmatched TOSAs. IC receives differential AC-coupled signals with on-chip termination. It can deliver laser modulation currents of up to 85mA at an edge speed of 22ps. Device is designed to have a high-bandwidth differential signal path with on-chip back termination resistors integrated into its outputs. An input equalization block can be activated to compensate for SFP+ host connector losses. The integrated bias circuit provides programmable laser bias currents up to 105mA. It is used in 10GBASE-LR SFP+ optical transceivers, 10GBASE-LRM SFP+ optical transceivers and OC192-SR SFP+ SDH/SONET transceivers.
  • Supply voltage range is 2.95V to 3.63V
  • Operating temperature range from -40°C to +85°C
  • Low power consumption
  • Programmable modulation current up to 85mA (5ohm load)
  • Programmable bias current up to 105mA
  • Programmable input equalization and output deemphasis
  • Supports SFF-8431 SFP+ MSA and SFF-8472 digital diagnostic
  • Integrated eye safety features with maskable faults
  • Bias current monitor
