Product Overview

The MAX3669ETG+ from Maxim Integrated Products is a +3.3V, 622Mbps SDH/SONET laser driver with current monitor and APC in 24 pin TQFN package. It accepts differential PECL inputs, provides bias and modulation currents and operates over a temperature range from -40°C to +85°C. An APC feedback loop is incorporated to maintain a constant average optical power over temperature and lifetime. The wide modulation current range from 5 to 75mA and bias current of 1 to 80mA are easy to program making this product ideal for use in various SDH/SONET applications. 2 pins are provided to monitor current levels in laser namely BIASMON with current proportional to laser bias current and MODMON with current proportional to laser modulation. It provides enable control and a failure monitor output to indicate when the APC loop is unable to maintain the average optical power. It is used at 622Mbps SDH/SONET access nodes, laser driver transmitters and section regenerators.
  • Single-supply operation of +3.3V or +5V
  • Operating temperature range from -40°C to 85°C
  • 40mA supply current at +3.3V
  • Bias current and modulation current monitors
  • 200ps rise/fall time
  • Automatic average power control with failure monitor
  • Enable control
  • Complies with ANSI, ITU and Bellcore SONET/SDH specifications
