DESCRIPTION
The X9522 combines three Digitally Controlled Potenti-
ometers (DCPs), and two programmable voltage monitor
inputs with software and hardware indicators. All func-
tions of the X9522 are accessed by an industry standard
2-Wire serial interface.
Two of the DCPs of the X9522 may be utilized to control
the bias and modulation currents of the laser diode in a
Fiber Optic module. The third DCP may be used to set
other various reference quantities, or as a coarse trim for
one of the other two DCPs.The programmable voltage
monitors may be used for monitoring various module
alarm levels.
The features of the X9522 are ideally suited to simplifying
the design of fiber optic modules. The integration of
these functions into one package significantly reduces
board area, cost and increases reliability of laser diode
modules.
