2.5 Gbps, 3.3 V Burst-Mode Laser Driver/Limiting Amplifier

2.5 Gbps Laser Driver and Integrated Limiting Amplifier in a 5x5mm QFN Package The M02090 is a highly integrated, programmable burst mode laser driver with a limiting amplifier intended for ONU/OLT applications up to 2.5 Gbps. The M02090 offers a single, flexible solution that addresses all PON applications of BPON, GEPON and GPON. Capable of independently driving 100 mA of modulation current and 80 mA of bias current, the laser driver in the M02090 can independently control bias and modulation currents via the Eye-Minder™, a dual closed-loop that maintains the target extinction ratio by compensating for laser aging, temperature, and voltage changes. Open-loop and average closed-loop configurations are also supported.
