FMM3193VI
DESCRIPTION
The FMM3193VI GaAs Laser Driver is a high-rate driver circuit designed
for fiber optic transmitters operating at NRZ data rates up to 2.5Gbit/s.
The FMM3193VI is capable of driving high-power Laser diodes at peak
current up to 80mA typically, and driving MI-Laser at peak-to-peak voltage
of 3V. The FMM3193VI outputs only modulation current, and an external
bias current circuit is required. This driver is assembled in a small outline
ceramic package having a similar footprint to SSOP-16.
