GENERAL DESCRIPTION
The ADN2526 laser diode driver is designed for direct modula-
tion of packaged laser diodes that have a differential resistance
ranging from 5 ? to 50 ?. The active back-termination in the
ADN2526 absorbs signal reflections from the TOSA end of the
output transmission lines, enabling excellent optical eye quality to
be achieved even when the TOSA end of the output transmission
lines is significantly misterminated. ADN2526 is an SFP+ MSA-
compliant device, and its small package and enhanced ESD
protection provide the optimum solution for compact modules
where laser diodes are packaged in low pin-count optical
subassemblies.
The modulation and bias currents are programmable via the
MSET and BSET control pins. By driving these pins with control
voltages, the user has the flexibility to implement various
average optical power and extinction ratio control schemes,
including closed-loop or look-up table control. The automatic
laser shutdown (ALS) feature allows the user to turn on/off the
bias and modulation currents by driving the ALS pin with a
LVTTL logic source.
The product is available in a space-saving 3 mm × 3 mm LFCSP
specified from ?40°C to +85°C.
