Description
The LG1625AXF is a gallium-arsenide (GaAs) laser diode driver to be used with direct modulated laser diodes in high-speed nonreturn-to-zero (NRZ) transmission systems. The device is made in a high-performance 0.9 µm gate GaAs heterojunction FET technology that utilizes high-density MIM capacitors, airbridge interconnect, and NiCr film precision resistors. The device contains three cascaded stages, operates with a single –5.2 V power supply and accepts ECL level inputs. Voltages control the modulated output current and laser prebias current. The LG1625AXF is available in a 24-lead hermetic, gullwing package. A test fixture (TF1006A) with SMA connectors is available to allow quick evaluation of the LG1625AXF.
