Preliminary Information

X9520

Fiber Channel / Gigabit Ethernet Laser Diode Control for Fiber Optic Modules

Triple DCP, POR, 2 kbit EEPROM Memory, Dual Voltage Monitors

FEATURES

DESCRIPTION

• Three Digitally Controlled Potentiometers (DCPs)

—64 Tap - 10 kΩ

The X9520 combines three Digitally Controlled Potentiome-

ters (DCPs), V1 / Vcc Power On Reset (POR) circuitry, two

programmable voltage monitor inputs with software and

hardware indicators, and integrated EEPROM with Block

Lock^TMprotection. All functions of the X9520 are accessed

by an industry standard 2-Wire serial interface.

—100 Tap - 10 kΩ

—256 Tap - 100 kΩ

—Nonvolatile

—Write Protect Function

• 2 kbit EEPROM Memory with Write Protect & Block

Lock^TM

• 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

—2.7 V to 5.5 V

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 vari-

ous reference quantities, or as a coarse trim for one of the

other two DCPs. The 2 kbit 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 monitors may be used for monitoring

various module alarm levels.

The features of the X9520 are ideally suited to simplifying

the design of ﬁber optic modules which comply to the Giga-

bit Interface Converter (GBIC) speciﬁcation. The integration

of these functions into one package signiﬁcantly reduces

board area, cost and increases reliability of laser diode

modules.
