Preliminary Information

X9522

Laser Diode Control for Fiber Optic Modules

Triple DCP, Dual Voltage Monitors

FEATURES

DESCRIPTION

• Three Digitally Controlled Potentiometers (DCPs)

—64 Tap - 10 kΩ

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.

—100 Tap - 10 kΩ

—256 Tap - 100 kΩ

—Nonvolatile

—Write Protect Function

• 2-Wire industry standard Serial Interface

• Dual Voltage Monitors

—Programmable Threshold Voltages

• Single Supply Operation

—2.7 V to 5.5 V

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.

• Hot Pluggable

• 20 Pin packages

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.
