IXLD02SI
Differential 2A Ultra Fast Laser Diode Driver
General Description
The IXLD02 is an ultra high-speed differential laser diode
driver. The IXLD02 is designed specifically to drive single
junction laser diodes in a differential fashion. A Q output and
a Q-Bar output are provided via a low inductance multi-pin
topology. These two signals make their transitions at the
same time with transition times in the picoseconds. This
technique provides the highest possible slew rate across
the diode. In addition the IXLD02 is capable of currents
exceeding 2A.
These performance features are combined with frequency
agility to a maximum operating frequency of 17MHz, a
minimum pulse width of <1.5ns and rise and fall times of
approximately 600ps. In addition, the pulse width and the
current programming can be modulated in real time to
>10MHz. The IXLD02 is assembled in a high power SO-28
surface mount package.

... Figure illustration of the pulse width vs. programming current. The programming current is typically a DC level, however it could just as well be a time varying signal. The bandwidth of this portion of the IXLD02 is equivalent to the maximum operating frequency of 17MHz. For the fastest response time this pin should be driven from a low source impedance ...

... The obvious caveat is that the pulse width must be consistent with the chosen frequency. This agility provides the designer with a broad range of design choices. Directed Energy, Inc.
