HY6410

The HY6410 Laser Diode Driver is a high speed, high current solid-state hybrid laser diode driver. It incorporates a patented technique of "backmatching" which allows remote drive of the laser diode through a 50 coaxial transmission line. This technique allows physical and thermal isolation of the laser diode and the driver. The laser diode can be driven through a transmission line without the need for a matched impedance termination. This removes a large source of heat that can be detrimental to high performance laser diode systems.

The HY6410 is used in applications that require digital, high speed, current modulation of the laser diode. Its input is ECL-compatible and is terminated into 50. The uses a GaAsFET current switch that drives a laser diode with modulation currents of up to 400mA peak-to-peak. Two programmable current sources allow user selectability of the bias and modulation currents. The pre-bias current is selectable from zero to 40mA.The Modulation current is selectable from zero to 400mA. These selected currents modulate the laser beam at the input frequency. The HY6410 comes in a hermetic metal package.
