1 / 12 page General Description The MAX3867 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. The synchronizing input latch can be bypassed if a clock signal is not available. An automatic power control (APC) feedback loop is incorporated to maintain a constant average optical power over temperature and lifetime. The wide modula- tion current range of 5mA to 60mA and bias current of 1mA to 100mA are easy to program, making this prod- uct ideal for use in various SDH/SONET applications. The MAX3867 also provides enable control, a program- mable slow-start circuit to set the laser turn-on delay, and a failure-monitor output to indicate when the APC loop is unable to maintain the average optical power. The MAX3867 is available in a small 48-pin TQFP pack- age as well as dice. Applications SONET/SDH Transmission Systems Add/Drop Multiplexers Digital Cross-Connects Section Regenerators 2.5Gbps Optical Transmitters Features o Single +3.3V or +5V Power Supply o 62mA Supply Current at +3.3V o Programmable Modulation Current from 5mA to 60mA o Programmable Bias Current from 1mA to 100mA o Rise/Fall Time < 90ps o Automatic Average Power Control with Failure Monitor o Complies with ANSI, ITU, and Bellcore SDH/SONET Specifications o Enable Control * Dice are designed to operate over this range, but are tested and guaranteed at TA = +25°C only.
