1.25Gb/s GaAs Laser Driver
FMM3171
FMM3171VI laser driver 1.2Gb/s optical transmission systems. GaAs MES-FET process allows high speed operation with power consumption. There data inputs options; complementary input single-ended input using selectable D-F/F. output duty ratio adjusting input reference voltage (Vref). differential mark-density monitor (Mmk) output proportional peak current output signal. peak current bias current output disabled shutdown terminal, which compatible. Logic "high" causes output disabled. High speed turn-on turn-off accomplished very compute time constant. amount peak current bias current monitored current flow terminal which must connected VSS. This FMM3171VI excellent choice laser driver OC-3/OC-12/OC-24 STM1/STM4 transmitters.
