+3.3V, 2.5Gbps SDH/SONET Laser Driver with Automatic Power Control
General Description 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
MAX3867
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.
