DESCRIPTION

The X9522 combines three Digitally Controlled Potentiome-

ters (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 vari-

ous 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.
