Functional Description
The LG1627BXC is a gallium arsenide (GaAs) laser diode driver to be used with direct modulated laser diodes in high-speed non-return-to-zero (NRZ) transmission systems. The device is made in a highperformance 0.9 µm gate GaAs hetero-junction FET technology that utilizes high-density MIM capacitors, airbridge interconnect, and NiCr film precision resistors.

FEATUREs
■ High data-rate clocked laser diode driver
■ Clock disable mode for data feedthrough
■ Adjustable high output current
■ Operation up to 3 Gbits/s

APPLICATIONs
■ SONET/SDH transmission systems
■ SONET/SDH test equipment
■ Optical transmitters
