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) trans-
mission systems. The device is made in a high-per-
formance 0.9
μ
m gate GaAs heterojunction FET
technology that utilizes high-density MIM capacitors,
airbridge interconnect, and NiCr film precision resis-
tors.
The device contains three cascaded stages, oper-
ates with a single –5.2 V power supply and accepts
ECL level inputs. Voltages control the modulated out-
put current and laser prebias current. The
LG1625AXF is available in a 24-lead hermetic, gull-
wing package.
A test fixture (TF1006A) with SMA connectors is
available to allow quick evaluation of the LG1625AXF.
