The MAX3869 is a complete, single +3.3V laser driverfor SDH/SONET applications up to 2.5Gbps. Thedevice accepts differential PECL data and clock inputsand provides bias and modulation currents for driving alaser. A synchronizing input latch can be used (if aclock signal is available) to reduce jitter.
An automatic power control (APC) feedback loop isincorporated to maintain a constant average opticalpower over temperature and lifetime. The wide modulationcurrent range of 5mA to 60mA and bias current of1mA to 100mA are easy to program, making this productideal for use in various SDH/SONET applications.
The MAX3869 also provides enable control, two currentmonitors that are directly proportional to the laser bias andmodulation currents, and a failure-monitor output to indicatewhen the APC loop is unable to maintain the averageoptical power. The MAX3869 is available in 32-pin TQFPand small 32-pin QFN packages as well as dice.
