Hot Pluggable  
Preliminary Information  
X9523  
Laser Diode Control for Fiber Optic Modules  
Dual DCP, POR, Dual Voltage Monitors  
FEATURES  
DESCRIPTION  
Two Digitally Controlled Potentiometers (DCPs)  
—100 Tap - 10 kΩ  
The X9523 combines two Digitally Controlled Potentiome-  
ters (DCPs), V1 / Vcc Power On Reset (POR) circuitry, qnd  
two programmable voltage monitor inputs with software and  
hardware indicators. All functions of the X9523 are  
accessed by an industry standard 2-Wire serial interface.  
—256 Tap - 100 kΩ  
—Nonvolatile  
—Write Protect Function  
• 2-Wire industry standard Serial Interface  
• Power On Reset (POR) Circuitry  
—Programmable Threshold Voltage  
—Software Selectable reset timeout  
—Manual Reset  
Two Supplementary Voltage Monitors  
—Programmable Threshold Voltages  
• Single Supply Operation  
—2.7 V to 5.5 V  
The DCPs of the X9523 may be utilized to control the bias  
and modulation currents of the laser diode in a Fiber Optic  
module. The programmable POR circuit may be used to  
ensure that V1 / Vcc is stable before power is applied to the  
laser diode / module. The programmable voltage monitors  
may be used for monitoring various module alarm levels.  
The features of the X9523 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.  
• Hot Pluggable  
• 20 Pin packages
