GENERAL DESCRIPTION
The ADN2525 laser diode driver is designed for direct modula-
tion of packaged laser diodes having a differential resistance
ranging from 5 to 50 . The active back-termination technique
provides excellent matching with the output transmission lines
while reducing the power dissipation in the output stage. The
back-termination in the ADN2525 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 mis-
terminated. The small package provides 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 power and extinction ratio control schemes,
including closed-loop control and look-up tables. The automatic
laser shutdown feature allows the user to turn on/off the bias
and modulation currents by driving the ALS pin with the
proper logic levels.
The product is available in a space-saving 3 mm × 3 mm LFCSP
package specified from 40°C to +85°C.
