X9520  
®
Fiber Channel/Gigabit Ethernet Laser Diode Control for Fiber Optic Modules  
Data Sheet  
March 8, 2005  
FN8206.0  
PRELIMINARY  
DESCRIPTION  
Triple DCP, POR, 2kbit EEPROM Memory,  
Dual Voltage Monitors  
The X9520 combines three Digitally Controlled Potenti-  
ometers (DCPs), V1 / Vcc Power-on Reset (POR) cir-  
cuitry, two programmable voltage monitor inputs with  
software and hardware indicators, and integrated  
EEPROM with Block Lock™ protection. All functions of  
the X9520 are accessed by an industry standard 2-Wire  
serial interface.  
FEATURES  
• Three Digitally Controlled Potentiometers (DCPs)  
—64 Tap - 10kΩ  
—100 Tap - 10kΩ  
—256 Tap - 100kΩ  
—Nonvolatile  
—Write Protect Function  
Two of the DCPs of the X9520 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 2kbit integrated  
EEPROM may be used to store module definition data.  
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 moni-  
tors may be used for monitoring various module alarm  
levels.  
• 2kbit EEPROM Memory with Write Protect & Block  
TM  
Lock  
• 2-Wire industry standard Serial Interface  
—Complies to the Gigabit Interface Converter  
(GBIC) specification  
• Power-on Reset (POR) Circuitry  
—Programmable Threshold Voltage  
—Software Selectable reset timeout  
—Manual Reset  
• Two Supplementary Voltage Monitors  
—Programmable Threshold Voltages  
• Single Supply Operation  
—2.7V to 5.5V  
The features of the X9520 are ideally suited to simplify-  
ing the design of fiber optic modules which comply to  
the Gigabit Interface Converter (GBIC) specification.  
The integration of these functions into one package sig-  
nificantly reduces board area, cost and increases reli-  
ability of laser diode modules.  
• Hot Pluggable  
• 20 Pin packages  
—CSP (Chip Scale Package)  
—TSSOP
