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.
