Description

The X9522 combines three Digitally Controlled Potentiometers (DCPs), and two programmable voltage monitor inputs with software and hardware indicators. All functions 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.
