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. The driver includes differential data and clock inputs. The high-output, low overshoot drive current and prebias can be set separately. Data retiming is accomplished by the internal flip-flop, minimizing jitter on the data. Clocking can be disabled for data feedthrough. A pulse-width control enables the user to compensate for laser turn-on delay.
