Using differential PECL data inputs, the M02067 supplies the bias and modulation current for driving an edge- emitting laser. The modulation output can be DC-coupled to the laser diode, giving a significant power saving over AC-coupled operation. The M02067 includes automatic power control to maintain a constant average laser output power over temperature and life. In addition, the modulation current is temperature compensated to minimize variation in extinction ratio over temperature. Output flags indicate laser end of life as well as failure of the APC circuitry to maintain average output power. Features • Rise and fall times <150 ps • DC or AC-coupled modulation drive • Independently programmable laser bias and modulation currents • Bias current to 100 mA and modulation current to 85 mA at VCC = 3.3V • Automatic laser power control, with programmable temperature compensation and ‘slow-start’ • Bias and modulation current monitors • Operates with +3.3V supply Applications • Gigabit Ethernet • Fibre Channel • 2 x Fibre Channel •GBIC Functional Block Diagram X100 X60 Failure Detect DIS ENA 55 55 FAIL X1 OCA DATA BIASMON MODMON IBIAS IMOD OUT- OUT+ VCC IBIAS RMPCSET VCC CMPC VREF PD OCASET RD GNDA RSHUNT CSHUNT VCC |
