Note 1: Operating the device beyond parameters with listed "Absolute Maximum Ratings" may 
            cause permanent damage to the device. Typical values indicate conditions for which the device 
            is intended to be functional, but do not guarantee specific performance limits. The
            guaranteed  specifications apply only for the test conditions listed.
           Exposure to absolute maximum rated conditions for extended periods may affect device reliability.


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 of IXLD02SI 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.
