MAX3668：+3.3V、622Mbps、SDH/SONET激光驱动器，带有自动功率控制

功耗最低的622Mbps激光驱动器

The MAX3668 is a complete, +3.3V laser driver with automatic power control (APC) circuitry for SDH/SONET applications up to 622Mbps. It accepts differential PECL inputs, provides bias and modulation currents, and operates over a temperature range of -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 of 5mA to 75mA and bias current of 1mA to 80mA are easy to program, making this product ideal for use in various SDH/SONET applications. The MAX3668 also provides enable control and a failure-monitor output to indicate when the APC loop is unable to maintain the average optical power. The MAX3668 is available in a 5mm 32-pin TQFP package as well as in dice.

关键特性 Single +3.3V or +5.0V Operation 38mA Supply Current at +3.3V Programmable Modulation Current from 5mA to 75mA Programmable Bias Current from 1mA to 80mA Rise/Fall Time < 200ps Automatic Average Power Control with Failure Monitor Complies with ANSI, ITU, and Bellcore SONET/SDH Specifications Enable Control
