| 2.5Gb/s GaAs Laser Driver FEATURES * * * * * * * * Operation DC to 2.5Gbit/s, NRZ Modulation Current Drive Only Capability to Drive Direct Modulation Laser and MI-Laser Maximum Peak Current of 80mA Typical@RL = 24 Peak-to-Peak Output Voltage, Min: 3V@RL = 50 Single-ended or Differential ECL Input Single-5.2V Power Supply Small Outline Package similar to SSOP-16 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.
