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.
