The MAX3869 is a complete, single +3.3V laser driver for SDH/SONET applications up to 2.5Gbps. The device accepts differential PECL data and clock inputs and provides bias and modulation currents for driving a laser. A synchronizing input latch can be used (if a clock signal is available) to reduce jitter.

An automatic power control (APC) feedback loop is incorporated to maintain a constant average optical power over temperature and lifetime. The wide modulation current range of 5mA to 60mA and bias current of 1mA to 100mA are easy to program, making this product ideal for use in various SDH/SONET applications.

The MAX3869 also provides enable control, two current monitors that are directly proportional to the laser bias and modulation currents, and a failure-monitor output to indicate when the APC loop is unable to maintain the average optical power. The MAX3869 is available in 32-pin TQFP and small 32-pin QFN packages as well as dice.

Applications

  • 2.5Gbps Optical Transmitters
  • Add/Drop Multiplexers
  • Digital Cross-Connects
  • Section Regenerators
  • SONET/SDH Transmission Systems

Product Detail

The MAX3869 evaluation kit (EV kit) is an assembled demonstration board that provides optical or electrical evaluation of the MAX3869.

The EV kit is composed of two independent sections on the PC board. The output of the electrical evaluation section is interfaced to an SMA connector, which can be connected to a 50Ω terminated oscilloscope. The output of the optical evaluation section is configured for attachment to a laser/monitor diode.

Applications

  • 2.5Gbps Optical Transmitters
  • Add/Drop Multiplexers
  • Digital Cross-Connects
  • Section Regenerators
  • SONET/SDH Transmission Systems
