HY6410
Laser Diode Driver
High Speed Laser Diode Driver
The HY6410 Laser Diode Driver is a high speed,
high current solid-state hybrid laser diode driver. It incorpo-
rates a patented technique of “backmatching” which allows
remote drive of the laser diode through a 50Ω coaxial trans-
mission 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 digi-
tal, high speed, current modulation of the laser diode. The
HY6410 input is ECL-compatible and is terminated into
50Ω. The HY6410 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 fre-
quency. The HY6410 comes in a hermetic metal package.
