1 / 37 page 02061-DSH-001-G Mindspeed Technologies ® July 2012 Mindspeed Proprietary and Confidential M02061 3.3 or 5 Volt Laser Driver Applications • SFP and SFF Modules • 1G/2G/4G Fibre Channel modules • Short reach and Metro SONET/SDH • CPRI: 614.4, 1228.8, 2457.6, 3072.0, 4915.2 and 6144.0 Mbit/s The M02061 is a highly integrated, programmable laser driver intended for SFP/SFF modules. Using differential PECL data inputs, the M02061 supplies the bias and modulation current required to drive an edge-emitting laser. The modulation output can be DC coupled to the laser diode. The M02061 includes automatic power control to maintain a constant average laser output power over temperature and life. In addition, the modulation current can be temperature compensated to minimize variation in extinction ratio over temperature. Features • High-speed operation; suitable for SFP/SFF applications. Typical rise/fall times of 55 ps. • Programmable temperature compensation. Modulation output and bias output can be controlled using a few discrete resistors. • Supports DDMI (SFF-8472) diagnostics • DC or AC coupled modulation drive. Up to 100 mA modulation current available when AC coupled. • Low overshoot allows high extinction ratio with low jitter • Automatic laser power control, with “Slow-Start” • PECL and CML compatible differential data inputs • Complies with major MSAs (GBIC, SFF, SFF-8472, SFP) including timing requirements • Packaged in a QFN24 • 3.3 V or 5 V operation • Pulse width adjustment Typical Applications Diagram Input Buffer VCC3 -1.3V Internal 3.3V reg.
